UNIQUE CUTTER JOINT DESIGN
The heart of a cutter is its joint, the area that joins the two halves of a cutter. All Tronex cutter models, feature a unique construction that includes four design elements:
Bearing rings are machined into the bearing surface of each cutter body. The rings face each other as the two halves are brought together. In cutter operation, over perhaps hundreds of thousands of cycles, the two halves only bear and move against each other over the very limited area of the bearing rings. Thus the metal-to-metal contact is minimized. Also, since the mechanical load from cutting the work piece is resisted at a near maximum distance from the cutter centerline, relative joint movement, or play, is minimized.
Hardened nut of alloy steel & extended cross-sectional area anchors the joint against movement under the cutting load. Precision machining of the nut insures perfect alignment of the two cutting edges.
Allan head screw with fine-pitched threads allows for perfect joint adjustment during initial manufacture and during resharpening.
Delrin washer eliminates metal-to-metal wear under the shoulder of the nut and reduces friction during operation.

RAZOR FLUSH® EDGES
Why exceptionally flush? When the end of a lead or wire must be soldered it is often necessary to have it as flush as possible to insure a highly reliable solder joint. If a wire is to be coated or if it needs to be threaded into some hole it may be necessary to have no burrs or "pinch" on the wire end. Delicate components are less likely to suffer shock when cut by an exceptionally flush cutter.
What is Razor Flush®? This is the name Tronex uses for the edge finish and anti-dulling protection on cutter models that cut exceptionally flush.
The two cutting edges on Razor Flush® cutters are finished with a delicate grinding operation to make them smooth, sharp, and in perfect alignment. The two edges come together much like two razor blades in opposition.
Adjustable anti-dulling protection is provided by a setscrew stop placed either in the handle or jaw of the cutter. The setscrew is adjusted at the factory to stop cutting edge motion exactly as the two blades come together. The setscrew thus prevents the blades from damaging themselves even when considerable force is applied.
