Hi Guys,
I am a plant manager for a printing company in Iowa. Today, I was replacing blades in our large gilloutine cutter, and realized one of our blades has now been resharpened so much, that it is too short to use in our cutter. Instead of recycling it, I was thinking of maybe having it waterjet cut down into some hand plane blades. The blade (similar to the picture below) is about 50" long, about 4" from spine to cutting edge, and about 1/2" thick. What are your guy's thoughts on the validity of using them as blades in shop made planes? The steel is high carbon, with an 18% tungsten content.
