I have heat treated 2 knives so far (both aldo 1095 in a paragon:) and yes there was scales i had to remove, but i could quench fast because i did not have to cut it out of a foil packet. Heat treat came out well execpt for the obvious scales i could not get out. The bottom line of my question (sorry) is will the time i have to cut out the blade from a packet and into quench really effect the blade performance (1084,1095,01) with these steels? I don't type for a living so please bare with my run ons. I have read the stickies, but would like some personnel opinions. Thanks for your time.

Clay, I don't know about your question, but I've wondered it too. I will be watching for a response.

Also, just so you know, that first "smilie" you posted is not allowed out of Whine & Cheese. It portrays a rather rude action. Lots of people make the mistake though. I think I needs to be made more clear in the smilie list.
 
Hey Medicevans, Thanks for letting me know. I saw the smilie and picked it, don't know why, lol. I thought it was a guy scratching his face, but now that i see it , duh. Oh well. I hope nobody gets offended.
Thanks

I have heat treated 1095 in 2 envelopes. Put the blade in 1 envelope but don't seal the top. Instead, make a larger envelope that will fit over the opening of the smaller one. It works pretty well and I can get the envelopes apart a lot faster than I can cut one open. I learned this on these forums and it worked pretty good for me. I hope this helps.
 
The blades will turn black but will be much cleaner than when heat treated with a torch. They clean up pretty easy. No hotter than you have to heat 1095, the foil is even in good shape when you are done. They say not to, but I have used the envelopes a couple of times before trashing them with no problems.
 
You absolutely do not need stainless envelopes for those steels.

I would use some light clay slip or a purpose made anti scale powder if anything.

You should not be seeing very much decarb in my opinion, excessive scale or pitting is probably a sign of a temperature control problem.
 
Daniel is telling the truth - at 1500°F, you don't need foil packets.
A slip coat of thin satanite ( the consistency of cream) will protect the blade from forming heavy scale. It will also help in speeding the quench with 1095 and other shallow hardening steels.
After HT, you need to drop back to 220 grit at the minimum ( I go back to 120) and start back up the grits in finish sanding.
 
thanks Bladsmth and Daniel. I didn't have any pitting just some scale that needs some sanding. This helps and i will try some satanite when i find some. I didn't want to spend the money on foil if i really don't need it and a faster quench will be easier. Thanks Clay
