A backlock knife like the delica might be converted. just cut away the "tip" on the blade I think. Here is a Ladybug blade to show what I mean. In my head the knife should work as a slip joint after.. At least I think it might work.
I think Vesp is right. A modified lockback will still retain some tension stopping the blade from just falling closed on its own. If you tried the same with something like a liner lock, there would be nothing stopping the blade from just falling closed on your fingers.
I e seen something similar on a British blades thread, but I didn't save the link. Basically as said you would need to grind the lock down a bit, but leave some to me the spring engage. Radius what's left to allow it to slip (this is the tricky part as too little and it's still a locker, too much and it's ruined) and probably reshape the spring to let it disengage too. I don't know how much tension there is in the lockback, but you may have to drill and pin/screw the spring to give it some more tension. Then you have a modified knife, but in the eyes of plod its may just be a well worn lock knife and so still illegal. If I was to do this I'd rehandle it to disguise the fact it ever had a lock. It could work though. ...Tapatalk signatures are like snowflakes - they're both very pretty...
Didn't Spyderco make a knife or three for that situation? There are some nice slip joint "traditional" knives too. From very servicable Rough Riders on the low end to GEC on the high end. I've never much thought of modding a locker to NOT lock....
Re: lock conversions. Thanks guys, some interesting thoughts there. I was thinking of something like a small sebenza or a mini grip kind of knife, which aren't as plentiful in the friction lock market as the traditional style. I'm also not sold on the slides o style yet (just choice, nothing wrong with it). Truth be told I've taken the liner out of liner lock and, yep, it's floppy. So unless some friction pivot can be devised those are out. The back lock does look a better bet. Deep subversive thoughts will follow. I'll post if I get anywhere. Thanks again, I truly much obliged to you all.
I bought that on a trip to S.America in '92. I did'nt have any tools. Don't get me wrong probably the best company in history. Everyone on the planet can recognize an SAk. This is all of them mumbo SAK by mumbojumboo, on Flickr
