If it is Hot-Rolled, the kinks can also be caused by hard spots.
1095 is commercially available in sheet as 1/8" and 3/16". I'm not sure about 1/4". It's cold-rolled with a #2 finish (nice, smooth).
Most vendors that I've talked to have it in 8ft x 2ft sizes. Most prices I've seen are right around $4.50 per pound.
example:

website says 1/8" maximum, guy on the phone said they could bring in a full sheet of 3/16".
At that price, and at those sheet sizes, you would be better off going to McMaster Carr. They have a 17.5" x 48" piece that comes in at about $4.50 per pound, last I checked. The smaller pieces are more expensive (per pound).
We have a shear at my work, and I would be happy to shear strips for you, but our shear will put a curl and a twist on anything narrower than 6". Admiral must be straightening their sheared pieces somehow (or not?). I could also laser strips for you, but the heat from the laser can buckle the metal too.
I brought up the subject of Admiral's sheared material, and my concern for flatness in a previous post. I got a lot of replies from people who said their steel was fine.
