Angle between ganja and pesi
Between the pesi (peksi) and the Ganja, there is an angle
Very often, if not always, there is also an angle between the pesi and the axe of the blade. What is the signification of this angle ? Why is it there ? How big is it and does that angle varies with the origin of production of the keris ? I have looked in my books but could not find any information on this subject. Can anyone give explanations ? Thanks, regards Michel |

Hi Michel, I'm not too sure what you mean by angle in this case .
This first example I've posted seems to be pretty much at a 90 degree angle to the ganja. Or do you mean the attitude or angle the keris blade assumes when dressed as shown in the second picture ? Rick |

Hi Rick,
Thanks for your answer. There are two angles to consider: The first that you mentioned with your first picture: is not 90°. It is systematically slightly off 90°. The second is the clearly seen on your second picture : If you prolonged the Axe of the ganja you have clear angle with the Axe of the blade. I have read something somewhere, but can't remember where and it was linked to fighting with keris. I do not believe very much in the fighting abilities of the keris and think that many of its Subtleties are derived from other reasons. But one never knows ! I am ready to listen to any valid explanation Thanks, regards, Michel |

Hi Michel, I was told by one of our members that this attitude of the blade is called Condong Leleh and that it relates to the gesture of sembah.
Perhaps our fellow member could comment on this as I do not wish to simply parrot information given to me by others. Rick |

This is just a theory based on biomechanics (part of what I do in my day job) and I am sure that there are symbolic meanings for the angle as well but here goes:
if you look at a fencing foil (it is probably the best example of a thrusting weapon still in use) you will find that the hilt is generally slightly angled as well, I cannot remember the angle but it is not great perhaps 15 degrees downwards. This angle allows the wrist to sit in a position where thumb, wrist and forearm form a straight line when the blade is pointing directly forwards (horizontal to the ground). Hence in a thrust/lunge you have the wrist in the most stable position at impact transferring the load up the forearm rather than through the wrist, you gain a couple of centimetres in elongation and you hit with the point directly forwards. The angle also allows you to have a handle/hilt that sits well in the palm or in the case of a foil allows you to use a pistol grip. Please feel free to pull this theory apart. cheers DrD |

I think you've hit the biomechanics nail right on the head .

There are actually a couple of angles involved here.
There is the angle that is formed by the base of the blade with the pesi, without the gonjo, and there is the form of the top of the gonjo. Where the thickness of the gonjo stays the same on each side of the pesi, the angle of gonjo to pesi will remain the same as the angle of blade base to pesi. The angle of pesi to the blade base in a modern keris varies from the angle of pesi to blade base in the keris buda. I proposed the idea some time ago that this variation occurred because of a basic difference in the way in which the keris buda, and its forebears, was held, and the way in which a modern keris was held. The keris buda was held in a way that allowed a strong downwards stabbing action to be used; the modern keris is held in a fencing grip that favours a thrust. I think that you will find the angles of pesi to blade axis set out in my "Origin" paper. The related angle, or perhaps more correctly, "form" is the form of the top of the gonjo. This form dictates the form of the top of the wrongko, and the form of the top of the wrongko is probably dictated by stylistic convention from era to era.This stylistic convention flows on to the desired appearance of the keris when worn.Maybe this becomes a "chicken & egg" question. Did the court stylists first determine thay wanted a larger curve and a more flamboyant wrongko, or did the court empus first decide that a more highly curved gonjo looked sexier?Or did they all work together to decide this direction? In the making of a keris, this angle of the pesi to the blade axis is determined by measuring the keris bakalan against a grid and setting the place on the bakalan for the point, and the place on the bakalan for the centre of the pesi; once these two points are set, the line for the base of the blade can be established. It is not a haphazard thing done by measuring with the eye, it is really done with a great deal of precision. |

angled to target?
Hi all,
Perhaps the angle was originally designed to incline the point toward the target when the blade was held at the side. The angle doesn't seem significant but it might have been sufficient to increase the chances of success. If what I propose is correct then the the angle parameters would be governed by the amount of inclination needed to keep the point on target during the thrust and limited by the amount of inclination that would cause the wrist to bend on impact. Perhaps the aesthetic evaluations derived from these mechanical necessities. Sincerely, RobT |

Michel, Rick & drdavid are correct that the angle of the keris is physicall biomechanic purpose. To understand this, you will have to understand how the keris is used for combat. In Malay martial tradition, when fighting using a keris, you are not to parry your opponent's weapon, but instead you side step to the especially left, or right. When stabbing your opponent from the left or right side, the angle will suddenly make sense.....
Philosophically, the downward angle also represents humbleness, the general character of the Malay people....humble but deadly |

I had an experience with the late Empu Djeno in Jogjakarta, in 1996. (It related to Rick's comment on "condong leleh", that I think Rick is right). At that time, I asked Empu Djeno to participate in our Tosan Aji (including keris) Exhibition in Bentara Budaya Jakarta August 1996, but he refused it because he felt too old (67 years old at that time) to leave his house in Moyudan, Gatak, Sleman Jogjakarta just to come to an exhibiton in Jakarta. He told me that he was very proud in the past, because the late Sultan Hamengku Buwono (HB) IX had commissioned two kerises to him. One with dhapur "jangkung mangkunagoro" (three luks) in 1984, and "sinom tuding" (straight keris with sekar kacang, with very sharp point called "nyujen") in 1985. On "condong leleh", according to Empu Djeno, HB IX had different bow with his predecessors, HB VII which was to straight, and HB VIII that was too bow... HB IX, according to Mr Djeno, chose in between (bow) of the two predecessors. Of course, HB IX didn't tell Mr Djeno, why this Jogja sultan asked him to do the commissioned kerises like that. But in the interpretation of Empu Djeno, the "condong leleh" showed the attitude of the gentlemen (who commissioned the keris) toward the society, or the environtment surround him. HB IX was too "straight" against the dutch colonial, and HB VIII too "bow" to the dutch authority... This is just my simple sharing to you, Michel... Ganjawulungt |

the right angle
Gentlemen,
Thank you for sharing these interesting explanations. They are diverse and sometime complementary. I will retain that: - there are biomechanical reasons related to the fighting use of the keris,that explains the angle between the pesi and the the blade. The angle I have measured on the images in "Keris Jawa antara mistic dan nalar" is 10° - This angle is not there for esthetical reasons but for the previously mentioned biomechanical one and is built very precisely. There I must acknowledge my ignorance of the word "bakalan" and as result, I do not understand fully Alan's explanation. (sorry Alan my Dictionary has not yet arrived). - The angle between the pesi and the ganja is the result of the difference of thickness of the ganja, of the position of the pesi on the width of the blade and of the previous angle. This position is precisely given by the "bakalan" and a grid utilized by empu and keris makers. I will find more on this in Alan's paper:"origin of the Keris" -If there is also a symbolic reason to the first angle (humbleness ?) the second angle seems to be there only as the result of the above given reasons. I am in the middle of a keris patrem forging and it seems that I will miss the exact positioning of the pesi on the blade as I did not know of the "bakalan" question. I think I can get the right angle , but my pesi will be a bit out placed. I guess I will have to live with that. A final question: what is the thickness of the ganja ? is there a rule or can I make it just esthetically ? Thanks to all for all these informations Regards Michel |

Hi Michel, I'm in the middle of building a patrem as well and I did the exact same thing with the pesi as you have, now the ukiran is made it looks better, you don't seem to see the "wrong" angle and placement as much! Have you laminated the blade and if so what metals/number of layers have you used?

A bakalan/calonan is a forging.There is a difference in the two words in Indonesian, but in English "forging" covers both. Go here:-
http://www.kerisattosanaji.com/PBXIIempus.html scroll to the bottom of the page and you will see what a keris forging should look like before it is carved. The angle between the pesi and the ganja can vary because of difference in thickness of the ganja on each side of the pesi, but in making the keris, the important thing is the angle of the blade relevant to the blade base. Before you start to make the keris you must make a pattern. You can draw this if you are a good artist, or you can use a suitable old blade and trace the outline.This pattern will establish the overall form and angles of the blade. To set the angle of the blade you take a line through the centre of the pesi and extend it past the point, you establish an angle of 90 degrees between the blade base and this line, in a normal sized keris of Surakarta style the point must fall between 5 and 6 cm. from the line.You cut your pattern to agree with the angle you have established, but you leave the top of the pattern above the blade base, uncut. You then draw the ganja that you want in its place. When you have drawn the ganja you may find that some slight adjustments to angles are required for aesthetic reasons. You make these adjustments. When you are satisfied with the form of the pattern, you complete cutting it to shape, and you are ready to begin forging your keris to shape. It can help if you make a couple of copies of the pattern and glue one of them to a piece of light flat iron. This will allow you to constantly check as you forge. The thickness of the ganja is an aesthetic consideration, but generally speaking, a blade with a thick ganja is regarded as artistically superior to one with a thin ganja, but bear in mind, one must have the experience to judge what is acceptable within the given parameters.You cannot just make "a ganja". You need to make the ganja to the correct form to suit the style of keris that you are making, and this style of keris needs to be governed by the parameters set by tangguh. If one does not understand tangguh it is probably best to find a blade that is pleasing to one's eye and copy that blade, or at least, use it for a guide. It is very, very difficult to make an accurate copy of a blade, but it is not so difficult to use a blade as a guide to help in establishing the forms that will appear in the finished blade. If the keris being made is not of a normal size, the angle can be established by scaling against that applicable to a normal keris, however, after this scaling has been done, it is virtually certain that adjustments to angle will be required. As a very broad aesthetic guide to the final visual impression that will be created by the keris, it should reflect the character, personality and perhaps physical build of the person it is being made for.However, this interpretation must be made within the parameters permitted by the style of the keris. |

Angle, forging, ganja
lemmythesmith
interesting that you are also in the same process. Yes my blade is laminated but I cannot recall the number of layers. They will be few (8 or 16) as this piece started as an exercise to heat weld nickel to iron. the pamor will be mlumah or parallel to the blade. I still have to lengthen the blade to fit my pattern that is next to the blade on the photo and follow Alan's explanations before starting the stock removal actions. I look forwar to see you blade when you will have completed it. Thanks, regards Michel |

Angle, forging, ganja
Thank you Alan for all the information.
I have now been on your site, printed some of the pages and I am learning a lot. I have also discovered that you give a glossary of Indonesian words related to keris which will be of great help at least until my dictionary arrives. Your article "origin of the keris" gives a very convincing explanation about the keris evolution and change of Angle between the pesi and the blade. I have a few problems to follow exactly your methodology for forging a keris, as I started making an exercise of heat welding that we transformed at a later stage into a blade and a blade not big enough to make a normal keris but only a patrem. I than had to find a good example of a patrem. I found it on Alam Shah site where he had one nice patrem with not too many luk and a thin and elegant blade, but no way to establish the angle between the pesi and the blade and a very special kerdas hilt. As you have seen on the photo, I do not have enough metal for the ganja and I will be iconoclastic again and forge it from a separate layered piece with no nickel. I will do my best to have this ganja as esthetically acceptable as possible. The example of Alam Shah, looks fine for me. I will have some difficulties with the selection of the hilt and sheath shapes. My inclination would be to make a hilt Jogjakarta or Surakarta style with a sheath ladrang, but I may be completely heretical with such a combination. I recognize that I do not tend towards perfection and excellence with that keris but as I do that for my pleasure, I hope it will not matter much and I will be pardon by you and the senior members of warung kopi ! Thank you so much for what you have explained and all the advices given. Kind regards Michel |

Michel, if you can phrase the problems you have in following my methodology as straightforward, specific questions, I will be happy to try to answer these for you.

Forging methodology
Thank you Alan,
Your methodology has a given chronology: 1) make a pattern of the blade, 2) set the correct angle between the pesi and the blade on the pattern 3) draw the ganja 4) cut the ganja pattern and adjust it 5) forge your keris to shape in summary you make a complete an exact pattern of the complete blade and ganja before starting to forge. I did that the wrong way, starting forging before having a pattern of the blade, let alone the one of the ganja and I am now with a piece of thick layered metal with the shape you can see on the photo and I will try to bring it to the shape of the pattern next to it. Secondly, as I have not cut the metal to make the ganja from my piece of layered metal and have already forge the pesi, I will have to make the ganja out of an other piece of layered metal from a previous heat welding exercise. This is all due to lack of planning as we did not start with the idea to forge a keris blade but to make an exercise in heat welding nickel and iron. But to our surprise we succeeded in heat welding a few layers and thought that it would be a pity not to utilize the results of our efforts. This is not going to be a reference keris (!) but the exercise will certainly teach me a lot. Thanks again for all your advices. By the way, we have moves the forge and the anvil from my place to my son's place and following your advices have now an improve forging situation. Kind regards Michel |

Hello Michel,
How about trying a ganja iras keris this time? That should fit with the stage you're at, and it's probably less difficult, anyway... Regards, Kai |
