Quench Plates (pair) Aluminum 1"x4"x16"
More than enough for smaller knivesI love the plate quench say good by to warp-age!
I usually heat treat in batches of 3 and this size of plate is the way to go for average size hunters in batches. If I'm doing a batch of large knives the plates get overwhelmed by the heat and you will have to dunk them in cool water, before the next quench (I throw them in the snow) and give them a quick dry before slapping a hot blade in them.
If you do lots of big knives or use thick stock I would go to the 1"x6"x16"

We bought some big planks of Aluminum (big) and cut them into sets of plates. Use these as quench plates for your air hardening steels instead of air or even oil hardening steels.
Tip: In use, place your knife from the oven, still in the pouch between the plates. Press flat with your hand. You don't need much pressure at all. Shoot compressed air all around in between the cracks. Your knife should be cool to the touch in just a minute or so.
Tip: I've heard of some guys putting their plates in the freezer before quenching. If get condensation on the plates and then place a burning hot packet of steel in contact with the water, you are going to have a dangerous out gassing of scalding steam. Best to avoid that. Keep you plates dry.
