Would recommend making up several coupons of a known blade steel (such as 1084 or W2) and HT at diff temps mark well and break. If done with care you can have a nice reference set. For a long time I kept a set for each kind of steel I used, but they seem to have found alternate residences over the years.
Most don't realize how drastic a diff 100 deg can make.....velvet to cornbread in 15 seconds if you are not paying attention.
