Tension Wrench Idea

[Fallen_Pin]

Wow, I've become quite a nuissence on this part of 101 ,
anyways, I'm a little screwed for tension wrench's, I have none to speak of and thanks to my inexperience, I dont know how to fashion a decent one, so then I got to thinking, could I grind away most of a key except for what inserts at the bottom? I've noticed a helluvalot of keys fit a helluvalot of doors, so I wouldn't have to worry about compatibility, the only thing that's stopping me from using this idea is the fear of strength.
Before I start to ruin a key, I was wonderin if I could get some input
Cheers

Street sweeper bristles.
Windshield wiper inserts.
Ground down allen wrenches.
Ground down welding rod
Ground down hacksaw blade.

bloody ell, I know what makes tension wrench's, I just dont know how to make em >=p . It's like trying to make your own lock picks for the first time without templates.
Anywho, Yes or No's would be greatly appreciated =)

some locks like the schlage everest for example are easier to pick when you use the bottom of a key or something that simulates the bottom of the key as a tension wrench - search on crypto.com (use google's advanced search - search for "everest" in crypto.com - I'm too lazy to do it atm...)

I think it would be a whole heap easier just to get a thin piece of metal (wind screen wiper blade etc..) and bend it using pliers into an L shape

go from:

to

much easier than filing down a key

Try these then.

These dimensions come straight from some of my favorite wrenches. These are all based on street sweeper/windshield wiper inserts. Width/thickness are up to you, as I have all of these in a variety of widths/thicknesses.

Bend to an L shape. I keep my angles at around 95-105 degrees. I like the slight offset, but you may find 90 degrees works best for you

Long part of the L 8cm 7cm 7cm

Short part of the L 2cm 1.5cm 1.25 cm

Roighto! I owe Chuck and White a cookie =) , Thanks guys, much obliged. Hehe, I knew the grinding key thing would work.. >=) Stupid little brother saying otherwise.
And as for time, my grandfather has a fantastic grinder that I've been using, so I can get a few key bottoms added to my tools in a matter of seconds =)

I would still suggest you make traditional wrenches for 99% of your picking. That being said, A key ground down FLAT to the lowest cut, leaving the full bow of the key, could be invaluable in turning the plug after the lock is picked. Many of us use a screwdriver or some such tool.

If my memory serves me, I believe Pyro's video shows how to make tension wrenches. Do a search for his video and view it.

Using a ground down key works ok, but you need a small rod and a hole to get decent tension. The rod can slip around a little bit and you may notice some false feedback when things move around a bit. I also wouldn't recommend grinding brass on the grinder. It might clog it up. I would say to use a dremel or similar tool with some cheap cutting discs. Don't forget to sand it smooth. Go ahead and give it a try, but I agree with the others who suggest a normal wrench. (Unless the lock is special like the Everest mentioned earlier.)

If you get a buch of wiper blades, you can experiment with different tension tool dimensions until you get what you like! You could always use the bottom of a key to get some measurements!? Have fun with it!
