Single-Action OTF Knives

Single-action OTF automatic knives are characterized by a blade that fires powerfully out the front of the handle at the push of a button (or equivalent). Compared to their double-action counterparts, they usually have firmer lock-up and fire more reliably and forcefully, at the cast of you having to manually retract the blade.
