Premium Cryogenically Treated A-2 Replacement Plane Iron
Give your bench plane a premium cutting edge with a handcrafted replacement iron from Roberts Fine Tools.
Each plane iron is individually machined, heat treated, cryogenically treated, hand finished, and sharpened in small batches in Colorado, USA. My goal is to produce replacement irons with exceptional consistency, edge stability, and ready-to-use performance.
Features
• Premium A-2 tool steel
• Precision heat treated in small batches
• Cryogenically treated for maximum transformation after hardening
• Hand finished with a fine satin surface
• Individually sharpened before shipping
• Laser engraved with the Roberts Fine Tools maker’s mark
• Handcrafted in the USA
Compatibility
Compatible with: Tested to be compatible with lie Nielsen Bedrock style #4 Smooth Plane and #5 Jack Plane as well as WoodRiver® V3 #4 and #5 Bench Planes (2" wide, 1/8" thick). May fit other modern planes as well but have not been tested.
Why Small-Batch Heat Treatment?
Unlike mass-produced tooling, every batch receives close attention throughout the heat treatment process, including:
* Controlled hardening
* Plate quenching
* Cryogenic treatment
* Multiple tempering cycles
* Individual inspection before shipment
Every blade is personally finished and sharpened before leaving my shop.
