In my intro post I described how my experience with sending my kitchen knives to a 'professional sharpener' got me back into the sharpening fold. Well... and this is difficult to say in this forum... They were Gerber Balance Plus. [Go ahead. Laugh. Get it all out of your system. There. Feel better?]
These knives have been all I've used since the mid 80s. Sure, they're heavy and far from laser-like, but when tuned up they've done a good job for me. The 10" chef's with aluminum handle fits my hand and is like an extension of my arm. And since you can find dull but like new pre-Fiskar Gerbers on eBay for chump change, my Edge Pro has a long career ahead of it.
My current problem lies with a cleaver. The sharpening service took it to a belt and tried to give me a convex edge. Which was more like a patchwork of random angled edges with no rhyme or reason. I really should have taken a picture of it for posterity. I figured I would match the most acute angle from the belt and use this cleaver as a heavy slicer or veggie chopper, since I have an identical cleaver with a stout angle for Western cleaver duty.
So I mount my DMT XC and giddyap. Lucky I had a 3 day weekend. After about 6 hours of working in sections I'm maybe 3/4 of the way to a reprofile. I even tried a freshly lapped EP 120 stone just for fun and the knife absolutely shrugged it off.
(Actually, at this point my fun meter was bouncing off the lower stop.)
I have used this DMT plate on 3 knives previously. Never applied any pressure, only allowing the (relatively substantial) weight of the plate to do the work. Always used wet. I DO work it on both leading and trailing strokes. I'm seeing swarf floating up and being washed away, but the progress is painful. Do you think I may have worn it down so soon (unlikely) or pulled the diamonds out with leading strokes as Ben Dale warns?
Finding accurate info on the steel Gerber used in the Balance Plus line is difficult. I'm pretty sure this stuff isn't the M2 high speed tool steel, but rather 440A with some attention paid to HT. Dying to know more.
Not having the common sense to call it quits, I have an Atoma 140 on the way from Mark. I'm hoping this weekend will be more fruitful than the last. Given the rather disappointing performance from the DMT should I restrict myself to trailing edge strokes until the diamonds have worn down some? I don't want to jack up another stone if indeed that is the problem with the DMT.
