Ian, I agree that this shows very distinct Spanish influence in the hilt. The blade (with it exaggerated curve) on the other hand reminds me more of an early to mid 1800's British Midshipman's Naval dirk. Unfortunately, sometime in its past someone cleaned the blade by using a wire wheel most likely mounted on an electric grinder. This has left a pattern of scratches over the entire surface of both sides of the blade. Normally I would just leave it as found, but instead I have decided to try to remove at least some of these for no other reason than to have it look a little more like it would have originally.
Detlef, you know me always looking for the strange and unusual. I am glad you like it and yes it will go into my personal collection with all the other Spanish influenced Philippine weapons I have been fortunate enough to acquire over the years.
I forgot to mention the fact that the blade of this is sharp on the outer edge only.
The only other Philippine sword/long knife that I can think of with an exaggerated curved blade like this are the more touristy looking ones sold as "Negrito Bolo's" on epray and other sites. Speaking of these, has anyone ever seen a really old example of one of these and not just the ones made around WWII and later? My thanks to everyone who have commented and given information on the original subject of this thread.
Best,
Robert
