Jim is at Blade show this week, so may or may not log in to answer.
BUT.... I'm pretty sure those are 12" tiles, so the blades should be 6.5-7" long.
IIRC, spine on the top one was right around 1/4" at the thickest point - it tapers a LOT fore and aft.
The other 2 were maybe 3/16" at the thickest.
scales are natural micarta
height is probably in the 2 1/4" - 2 3/4" range, depending on which one you're looking at.
the top one is definitely heavier, but still lively due to balance point -- even do, it's more choppy.
the other 2 are thinner and lighter - very slicey and fast in the hand.
the bottom one also has very flat scales. the texturing gives it a nice grip, though.
nope - it's been a year since I last handled them.
if you want a fighter/kata knife, go with the sculpted handle one if it's still available.
if you want a GP food prep/camp utility/hunting knife, the other 2 are more comfortable for prolonged use.
