  1. a great light field bowie/combat knife... 5 Star Review

    Posted by on 1st Mar 2014

    this is a tough knife, emphasis on "tough" over "knife"....had one decades ago and threw it thousands of times as a kid and never broke the point, after half a decade of often flat buzzing strikes against telephone poles, it finally broke tang inside handle, and even that may have been a bad heat treat batch rather than knife design problem..

    the tip can handle prying open a can of paint with no problem, edge is thick and unlikely to ever chip or break out....which doesn't make the best chopper with deep bite, but no deep biting chopper of a knife has an especially tough edge when it hits a nail or hidden screw/bolt.

    this knife could be beat point first through sheet metal and suffer nothing but dulling.

    grinds are very good and straight and symmetrical, only slightly thicker to one side, edge sharpening is very wide angle and could use rework to 30 deg, which i did to mine

    cannot be beat for the money. i ordered another Ontario after playing with this one.

    Recently I purchased this knife. I have owned one many years ago when I was in the U.S.Army.This was the mostdurable and utilitarian knife I ever owned. It's well made, balanced perfectly, and is a classic. I recommend this knife as the ONLY knife a person will EVER need and want. Thanks OKC for and outstanding product

    Many years ago, when I was in the U.S.Army, I had the great fortune to have this exact knife. It served me in every capacity. It never failed me. Men in my unit were so impressed with it , they started buying their own. It takes and hold an edge well, it's well made, rugged and extremely dependable. I would highly recommend this knife to servicepeople, outdoorsmen, survialists, and anyone who needs and values a well made , durable, dependable knife. Thanks for and outstanding knife.

    excellant. the handle is actually centered over the blade unlike k bar.this is the closest ive seen to a ww2 mil grade fighter.no frills ready for the field and some use. with proper care this one should hang in there. havent tried to batton any california redwoods yet but seems better suited for fighting.no better field knives than uncle sam tested and approved.

    This is a great knife for field use.
    The clip point is sharpened on the top too which is rare.
