I have an old old timer 340t that has some pretty bad wobble in it. Is there any way to fix this?
 
Could I still use it and not break it? Does the bladeay really harm the knife, like coud it actually break it if I used it.

For what you'd use it for day-today, it will probably last your lifetime. I have a bunch of old U.S. Schrades, most are tight, but a few have significant blade play side-to-side. They still open & close & cut just fine. Typically (in my experience, anyway) knives built with the Swinden Key system will loosen to a certain point, and not loosen up any further.

Someone, a few days ago,brought up the Swinden key. They said that the Swinden key was used in a lot of knives, including the Imperial KampKing. When i was a boy, my knife was a KampKing. The blade deveoped a lot of play because i used the knife very hard . One day i was bearing down,atempting to press the cutting edge through a tree branch. The blade actually squeezed backward between the spring and liner causing the blade to pivot over backward (folded over backward). I was aghast,as this was my one and only knife. I managed to pop the blade back into it's proper position. Blade play fom hell, up and down and side to side. Feeling that the knife was ruined and that i couldn't hurt it worse than i already had, i put the bolster in a vise and tweaked the knife, pulled it and checked it. I continued slightly tweaking (slightly pinching the bolster) again and again. After doing this VERY slowly and methodically, i sucessfully took most of the blade play away. I was able to use the knife for 3 or four more years. I still have it (that was forty years ago) it still works. Hope you understand my explaination, hope it helps. SLOW AND EASY TWEAK AND TEST. regards Henry
 
Thank you everyone for the help especially Henry. It gives me hope that I will be a ble to use it.
