If you would like me to heat treat your blades, please read carefully below first.
Steels I can heat treat are O1, D2, 440C and EN42 I have supplied. All blades and springs must be clearly marked with the steel and the sender.
I can heat treat knife blades and folder springs. The cost is £4 for the first blade and £3 for additional blades in the same lot. Folder springs are the same cost. Postage costs are extra.
The minimum finish on the blade before heat treatment is 320 grit or finer all over the blade. It must have no sharp corners or deep scratches all of which can cause cracking. All holes must be chamferred.
Blades must be straight before being sent. I cannot straighten blades or regrind them except by prior agreement and an additional charge will be made.
The blade must be evenly ground on both sides to prevent warping. Blades should be wrapped in paper and cellotape or packaging tape, please no duct tape. All blades must be thoroughly degreased. It is not necessary to have any oil on the blades.
The blade will be hardened to Rc 58-62 and there will be some surface oxidation. Blades will be the same hardness throughout unless otherwise agreed beforehand. Blades can be made harder or softer by prior agreement but additional charges may be levied.
I cannot be responsible for any damage to the blades I heat treat but if I think there is going to be a problem, I will let the client know before starting any work. A handling charge may be levied at my discretion if blades prove to be unsuitable for heat treatment. Turnaround time for the blades will be 3 weeks or less. The maximum overall blade and spring length is 250mm unless agreement for longer blades has been made beforehand.
I reserve the right to reject any blades at my discretion. Payment for the service must be made one month or less after the blades have been heat treated or additional storage costs will be incurred. Blades that have not been paid for after 3 months will be disposed off and all proceeds will be retained to pay for storage and heat treating costs.
Please email me for further details.
Good luck!
