First DIY torsion wrench

[hda7]

My second attempt at a torsion wrench (in my first attempt, I found out that tungsten hacksaw blades don't bend; they break). The bend could have been made better (the blade cracked slightly), but overall I think this is a good first attempt. Comments and suggestions are welcome.

Have you tried windshield wiper inserts? Much easier to work with, and around the right thickness for most US keyways.

I have head about windshield wiper inserts, but I do not have any available yet. My dad gave me four old hacksaw blades, so I figured I'd try to make something. It's my first successfully made lock-picking tool (if you don't count paper-clips ), and I'll try to make a pick or two later. I'll post pictures if it turns out well.

Just the fact that it works is something to be proud of.

My only comment is that as someone whose luck with sharp objects is not so great, I get a little freaked out by the fact your tool still appears to have teeth. Maybe you could tape it or something.

I did it on a Dremel-tool with a cutoff wheel, and I didn't want to try to cut all of the teeth off. I probably will wrap it in electrical tape.

My first tools were hacksaw blades dremeled and taped too.

Heck, even with a variety "proper" tools now, I still use one of those on wafer locks

My first pick (other half of the blade):

Congrats for your first pick, I like it Did you sand it? Round off all the sharp edges with fine grit sand paper

Cheers

hey, I recommendjust like many others to use windshield wipers, I made 6 tension wrenches out of a half windshield wiper and they work good for most locks.

I also made a tension wrench out of a reading glass frame (2 pair of reading glasses for 0.88 euro cents so i can make 3 more ).
On most cilinder locks this one works better cuz its slightly fatter so it won't get diagonal in the lock.

BTW here's an photo:



The lefty is the one from the reading glasses the rest is from windshield wipers.

Yes, I did spend some time on it with 400 grit sandpaper.
It works great for my Kwikset cylinders.

My next attempt:


I'll probably make one out of a windshield-wiper insert next; I should be getting some soon.

I finally got some made of windshield-wiper inserts. I'll post pictures soon.
