Z Coined Cold Knife Blades (2024)

FAQs

What are Z blades? ›

Z blades will remain flexible and retain their sharpness much longer than the average cold knife blade. The grinding of the blade is at a greater angle than other cold knife blades. This makes the resistance less when pulling the cold knife to cut the urethane.

Cold saw blades are used to cut metal using a relatively slow rotational speed, usually less than 5000 surface feet per minute (SFM) (25 m/s), and a high chip load per tooth, usually between . 001"–. 003" (0.025–0.08 mm) per tooth.

Why So Many Blades? The older style pocket knives were made to fit the line of work of their owner. In other words, the blade configurations on your knife reflected kind of work you did.

Japanese blade sharpness is a result of their higher carbon content – the more carbon in the steel leads to a harder steel which can be sharpened to a finer edge. Western high carbon blades usually have less than 0.8% carbon – making them relatively softer.

A cold saw provides superior cuts

Cold saws, with their toothed blades, make clean cuts without burred edges. While abrasive blades tend to wander, even on straight cuts, the toothed blades are much more dependable on straight or angled cuts.

A properly maintained cold saw blade should last a long time, even with extensive use. Circular cold saw blades can endure as many as 800 to 1,000 cuts before needing to be sharpened, and they can be sharpened up to 30 or 40 times during the lifespan of the blade.
