Ontario swords are 1095 carbon steel, .187" thick hollow ground and not differentially heat treated. I have their katana which is the same dimensions as your wak. Bought it before I came across your website. I like it! The Jager sword is a khukri-type blade with same construction only it's 15". after wrapping the tsuka in 550 paracord I have no complaints! But I'm interested in something shorter. Noticed that G-19 Bowie of yours!! Man, that's a blade. Also that Gladiator is impressive also. Was wondering how the blade rests in your kydex sheaths? Does it lock in or just rest in the scabbard? My Ontario katana locks into the sheath with the side flanges near the handle locking into the sheath. Maybe I'll just save up a while and go for one of your Bowies.
