Medina2928 Posted September 14, 2016 Share Posted September 14, 2016 I have a friend that can get all the cutting edges I want from motor grader and bulldozers. Does anyone know if they will make blade steel. Quote Link to comment Share on other sites More sharing options...
Frosty Posted September 14, 2016 Share Posted September 14, 2016 Yes I know if grader, dozer, etc. edges will make good knives. NO it won't, it's the wrong kind of steel on almost every level. The stuff is first abrasion resistant at a level that will just eat grinding wheels, cups, belts, etc. unless you're willing to spend the $ for blue. Then it's impact resistant to the point of stopping 72,000lbs. of 30mph Cat 14d road grader within a couple inches of snagging a manhole without bending. With some imagination you can make a workable shear with it. If you need to grind it low read heat and a stone cup are your best bet. The stuff is tempting but it's designed so "perfectly" for what it does it's not much good for anything else. I have a couple few pieces if anybody's interested. Frosty The Lucky.

Michael Cochran Posted September 15, 2016 Share Posted September 15, 2016 I have six in my yard I planned on using for tooling. I knew I didn't want to make knives with them but tooling of all sorts can be done provided you have the patience and tolerance for abuse. I used a whole cut off blade on my grinder and made a 3/4 inch cut across one and haven't tried any more. Quote Link to comment Share on other sites More sharing options...
aessinus Posted September 15, 2016 Share Posted September 15, 2016 Only thing I have is grandpa's posthole diggers. Schedule 80 pipe handles & 3/4"square bar for a box hinge. Forged grader blades for the shovels. Those things will dig thru pure shale or limerock, no problem, but you'd better have your big-boy britches on.
