Over the years, Virginia custom knifemaker Ed Van Hoy has conceived a number of award-winning designs for CRKT, including the highly successful Snap Lock™. Ed is always thinking, and coming up with original ideas, and his new Yea-Go™ is a perfect example. Yea-Go is a Navajo phrase meaning "all your might" and Ed has certainly put all his might behind this one.

First he invented an entirely new patent-pending mechanism he calls the Arcuate Opening System (1) (A.O.S.™), which is a new advance in the world of assisted opening that is so popular today. It uses a unique arced internal frame slot and a spring-mounted blade pivot, which together allow the blade to be opened instantly by just a flick of the contoured thumb disk. The locking liner crisply snaps into place.

Opening is simply a matter of pressing down on the thumb disk and releasing it quickly with a slight forward flick. The blade is safely stowed when folded, and casual pressure down on the blade does not actuate opening. One-hand closing is quickly accomplished as with any locking liner folder.
