Admiral crooked Steel

I bought some steel from Admiral Steel to make a small kitchen knife for my wife. First I only purchased from them because they were the only ones I found that offered ATS-34
in the size I was looking for 3/32x1" When it came it was bouncing around in a cardboard tube and of course it was bent. Next it wasn't 3/32x1" it was more like 3/32x31/32 My pattern was for 1" so I had to modify my pattern. Now what to do about my knife. Can it be straightened during heat treating or what can be done? Its not visibly crooked but when you put it on a flat surface it's quite noticable. Don't believe I'll be buying from Admiral Steel again.

It should have been very easy to straighten after you profiled it. If it bent in heat treat, it is easy to straighten while cooling - wait until the red color just leaves the steel and then straighten quickly.

Sheffield's Knife Supply has Ats-34 in 3/32nds sizes ......

Bent bar stock is very very common. Almost every bar of steel I get has a bend somewhere. most of the time, it can be just worked out as you form the knife whether by grinding or forging. But sometimes the bend is so extreme you have to straighten it out first. Thin barstock is bad for this but just as it is easy to accidentally bend, it also easier to bend back. Annealed bar stock for grinding is simple enough to put in a vice and gently strong-arm it to the right shape.

Steel that bends or warps during the heat treatment is ANOTHER ISSUE ALTOGETHER AND IS THE TOPIC OF MANY DISCUSSIONS HERE ON THE FORUMS.

On the other hand, if you are buying PRECISION GROUND stock, it should be dead flat - after all thats what you are paying all the extra $$ for. NEVER accept precision ground stock that comes to you bent.

Just my thoughts. Jason.
