Straightening soft blade

[ernestrome]

Any tips on getting an unhardened blade back to straight after unintentionally bending it? It is mostly straight now but has a very slight s-shape.

I'm sure there are better ways but this worked for me. Mind you, I only had a single U bend and not an S but maybe you could improvise. I just clamped one end of the blade to the table and put a drill bit in the middle of the length of the blade. I then clamped the other end down and waited a little bit. I then progressed to larger bits, I think ending at 3/8", until it was straight. I'm new to this so add the proverbial grain of salt.

Never tried it but similar to striders answer is Wayne Goddards jig. He uses three rods two on one side and one on the other in a vise.

I use the 3 point jig as mentioned above, works really well really simple to build.

Here is how I straighten blades.

Thanks for your advice. I am troubled by two small bends over the length of about an inch.

Maybe if I had asked before trying to straighten the original simple bend I wouldn't be in this position. Given that I am, how would you tweak these little bends back to straight?
