New way to polish blades?

There are a lot of strangely abrasive things out there like that. A lot of plastics are extremely abrasive, we just don't cut enough at one time to see the effects. I did polyethyline extrusion for a while (made plastic film like retail bags, food packaging bags, etc) and the machines that make that stuff make millions of feet of plastic a day, and on the end of that machine the film gets split into rolls by cutting it as it winds onto a roll. The cutting is done by a specially shaped razor blade (never did know if there was anything special about the steel on those blades). After a few thousand feet, the blades would be mirror polished on the sides and they would dull pretty fast for cutting fraction of a millimeter thick plastic.
Another good example is good old Mr. Clean Magic Eraser, aka melamine foam. That stuff has been used for decades as a sound deadening material in recording studios. Whoever figured out it had abrasive properties and made a good surface cleaner probably happened upon it by cutting it like you did. Maybe someone's patina was rubbed off and now they're a billionare for selling the idea to Proctor & Gamble.

Plastics are what some of the abrasive, corrosion resistance steels were introduced for.

Yes and if you use the blue kind that has reflective metal film on it it makes my knife dull a lot faster than I would have guessed...mattman wrote:My brother and I were insulating his garage with some blue poly-board, and cutting it with our knives, and we both noticed how it was making the blades quite warm on long cuts...

Another thing that dulls blades quick is cutting up old used carpet. Between the fibrous backing and the grit that has accumulated in the carpet, it will dull almost anything pretty quickly. My M4 Mule lasted a couple of hours, but it started getting hinky before lunch...
