I cant imagine anyone not appreciating a well made traditional slipjoint and I am no different, I think they look fantastic and though I only own one (Case Stockman) and have never made one, I always look at the ones posted with admiration - one day!
I have made sketches of several designs but have never got as far as making one. The reason being that I always get stuck with the spring design - why does it have to be flush?
It makes sense to have the spring nice and flush in the open position but why when it is closed?
If you could have the spring sitting a mm or so low in the closed position, the knife will be easier to open and could be made to close in a safer more controllable manner. Both without sacrificing security in the open position.
Would this still be a traditional slipjoint?
