Ethnographic Arms & Armour

posted this one of mine on another board last year, someone just bumped it up, thought it was cool. i posted back with some more detail, and now thought i'd post here as well. this is a relatively new blade, i've had it for a few years but suspect it's been made this century.

the bolo tusok weighs 1.75 lbs. (780 gm) without the sheath. blade is roughly 1/4 in. thick at the guard, 1 3/8 in. wide at the guard, 1.5 in. at the first 'hump' on the spine and 1 5/8 at the hump nearest the point. thickness is distal tapered from the guard to the point. blade is 16 3/4 in. long. grip is 7 in. long, nicely figured very dense and dark brown wood with black stipes.

the bolo is allegedly a 'tusok', meant for stabbing, tho it's heavy and substantial enough to cut. very well made and full convex grind. it's signed,
looks a bit like a rearing cobra with two cuts across it. see attached. does anyone recognise the mark? i assume it is a contemporary maker in the phillipenes...
