Thread: Profile Techstudio Sharpening System - feedback?

What do you want to sharpen? Knives?

I have a similar system to the PT one, a Lansky, and it works OK, but I find it tedious to use on knives, especially kitchen knives (my wife will cut on granite and destroy the edge in seconds!).

A few weeks ago I purchased a simple tool from Lee Valley, called a Universal Sharpener ...



This has a carbide blade, and is used like a scraper. "The action is like using a cabinet scraper instead of sandpaper to smooth wood".

I have used it on kitchen knives and pocket knives. It takes a few seconds to do, and it leaves a sharp edge. It's good for these edges (and probably scissors), but not necessarily for others.

I've been doing that for years in my kitchen. Lee Valley 70M46.50 knife sharpener. Did not know they had a newer one. Thanks.

On mine, the active t/c is a pair of squares with tapered edges. You can remove the mounting screws and rotate the squares to fresh edges but I never have.
The deal is that the scraping over the pair gives you a repeatable bevel angle on both sides of the knife at the same time. For cheaper, softer steels,
these tungsten carbide scrapers can't be beat. They really spall off visible shreds of knife blade. Plus the blade really doesn't need to be either clean or dry.
Leave it like that with some tooth for veggies or refine the edges for meats.
