Most wrenches are made of hardened vanadium carbon alloy steel. AldenWrench is made of Stainless Steel (17-4pH). This stainless alloy is widely used in aerospace and in many industries. It's limited hardening capacity, usually up to 38R.C. and rarely 40R.C., makes it an ideal stainless steel tool. Most wrenches are mass produced and chrome plated. AldenWrench has NO chrome nor cadmium plating, a basic requirement for use in aerospace. Chrome plating creates a shiny and appealing look when new. However, it will eventually form chrome chips when the tool ages. Chrome chips can interfere with sensitive mechanical and electrical function. The shine you see with the new Alden Wrench is a result of hand polishing. Yes, all AldenWrenches are individually hand polished. Although easier scratched compared to chrome plated wrenches, the shine can always be brought back by re-buffing the AldenWrench. Most open ratchet wrench needs an open room or swing angle of 60 degrees to work. AldenWrench needs only 30 degrees room to ratchet. No one else comes close. Coupled with small head size and a design with increasing interactive grip. It sets a new standard in the open end ratchet system. In order to work, wrenches should be very hard and form a close tolerance fit with it's equivalent fastener size. AldenWrench does not need the hardness of most commercially available wrenches. It is usually softer by -1to -2R.C. Why? It's unique interactive design creates a prying-like action of a fulcrum that transfers the force applied to the handle as a gripping action to the fastener. How? Because it grips more as more force is applied to the handle, it's grip is better than most regular open wrench. Of course Alden can make it out of similar less expensive steel, but since these wrenches changed the rules, they might as well change it all the way... for good!
