The same kinda locking that the screwdriver on Wengers enployes would work, wouldn't it?
On second thought, any locking mechanism would be prone to breakage/failure when subjected to the stress of turning a nasty bolt, so maybe it's better to force the user to turn the knife around and exert the pressure against the substantial backspring? Def
I don't know if you are aware of this, but I believe that the Surgeon General has decreed that agreeing with me might be an early symptom of senility. ;DDef
If you do I am certain many things in your life will start to fall into place! ;DDef
