Columbia River Knife and Tool 5150 Hole in One
Columbia River Knife and Tool's 5150 has a high flat grind with a gently curved Razor-Sharp edge. The model 5160 single-hole blade is plain for easy cleaning, while the fancy model 5150 receives five lightening holes in the blade spine.  The Hole In One's locking mechanism locks both open and closed. Most important, when the knife is gripped tightly during use, the lock also grips tighter for increased safety.
