(Wow! I should have checked my spelling on that last post... needed more coffee.)
I like windshield wiper inserts myself as well. I like just a little bit of spring in my wrenches but not too much. I use a double ended standard wrench most of the time. No twist-flex style at the moment. my double ended has a thin and a thicker side. Gonna make some twist-flex soon.
I don't know who to give credit for the idea, but putting a gentle taper to the business end of the tension wrench can help it fit different sized keyways. I read it here someplace. Simple and effective! Great for an emergency kit or just to keep down the number of wrenches you need.
There are many other styles of tension tool. Do a search and check the lockpick manufacturers websites if you have not already. You may like some of the alternatives
My friend's brass rod tension wrench worked surprisingly well, so if you have brass rod lying around, go ahead and give that a try as well if you wish. I used some anti-sway bars from an rc car and they work pretty well. They are just metal rod with some bends. I cut them in half and made 2 wrenches from each.
Tension tools made from metal rod have a nice feel. Try different things when you can and use what feels the best! Remember, you should be feeling the feedback from the wrench and the pick both. You even get feedback from the lock itself if you hold it in your hand. (Like with padlocks or removed cylinders from deadbolts, etc...)
Once again, congratulations on opening that lock! Sounds like you are headed in the right direction!
You learn more when you make your own tools in my opinion! Welcome to the hobby!
