I don't think you can get the steel hot enough with the Worksharp to ruin the temper, A grinder is another matter.I use a stone followed by a very fine ceramic stone. My 30 year old Buck 110 has never been dul and it holds an edge. Blade looks nearly new. I always was taught motorized sharpeners take the temper out of the knife’s edge and it gets dull faster so you sharpen more and then the knife isn’t any good. Am I missing something or just plain wrong.
I just sharpened an 18” blade machete with one. You just have to move the blade a lot. It took me about 75 minutes to get to a razor edge. It will cut down a 3” tree with one or two whacks.I used a Lansky for years, and still do but it's sometimes hard on large bladed knives. I've been use a Spyderco Sharmaker for the past few months with good (for me) results.
What I failed to mention in my original comment is Darex makes the worksharp and they also make twist drill grinders. I have one of the professional models. Not cheap (500 bucks) but works well for 90% of the HSS twist drills I need to resharpen. The rest I sharpen offhand. All Darex products are good American made tools.This gadget from Cabelas is made in Oregon. It uses small carbide belts to grind down any metal. A honing belt delivers a razor’s edge.
The coarse belt restores an abused edge. Two cassettes ensure the right angle for knives, scissors, etc. Belt changes take perhaps 30 seconds.
Not cheap at $89. But it flat works, and deserves the 5 star reviews.
Tomatoes, oranges and an apple yielded thin slices on 3 knives I put to the test. View attachment 308553
We have a strop here also, but Kenneth when he has time to do it up properly also always shaves with a straight razor otherwise if in a hurry he uses just the cheapest disposable he can find. He grew up watching his Granddad do it that way and just found the whole procedure with the mug, brush, and lathering up interesting and fascinating.I use what you use Wendy, followed with a leather strop. Same one I use to hone my straight razor.
Yup! I've got one like that too.This works great for us:
We already have more than a few Spyderco knives so the sharpener was a natural addition!
