Need a little help. I’m just not sure what this type of knife is called and I have a customer that would like me to locate him several more for his business harvesting vegetables.
Looks like a Kukri.
I bought one once from Connecticut Valley Arms (CVA) back in the '70s. It was called a buffalo skinner.
Kukris have roughly the same profile, but the sharpened edge is on the inside of the curve.
Thats it! I posted originally from my phone and should have mentioned the size was 6" blade and 4" handle. I had assumed wrongly that the cutting edge would be on the inside curve for vegetable harvesting…so I called him.
Turns out it exactly the one you posted! Looks like they are going to order a few more and send a couple at a time down to me for a tune up. Thanks you guys!
