For a couple of years, I've been getting out my Razor Edge Systems kit when a blade needed re-profiling. The RES benchstones do a great job at re-profiling an edge, but the guides that come with the kit don't give the same angles as the 204, so it was an un-comfortable fit. And getting the guides on the blade just right wasn't a simple task. Get it wrong, and I ended up with some uneven bevels. Usually, the bevel thinned out noticably as it approached the tip. What a pain, but it was the best solution at the time. An Apex might've worked better, but I couldn't bring myself to pay that much for something that I couldn't easily carry with me.
So I was rather excited when the little brown truck showed up this evening with my ultrafine rods and diamond rods. Being diabetic, it was all I could do to eat dinner before taking on a blade. Wolfing down dinner so that you can get to sharpening a knife is normal behavior, right?
Anyway, I sat down, expecting to be able to do a good job re-profiling, but wondering how long it would take compared to the RES stones. After all, they might not match the 204's angles, but they will rebuild an edge on even 440V rather quickly once the guide is set. I gave one side about 30 strokes on the diamond rod, then stopped to see how I was progressing. The blade wasn't in bad shape, it just had that factory grind of another popular brand that has a reputation of being, well, thick and sometimes rough. I was shocked and grateful at the same time. I'd already taken it down to the edge and had a burr the full length of the blade! No telling how much steel I needlessly removed. I know that sounds patronizing, but the truth's the truth. It took about 20 strokes on the other side to bring that edge down to a burr. In less than 5 minutes, I was finished with the job. I could not have gotten the RES kit out and set up that quickly, much less have the blade re-profiled. And it's no where near as handy to carry as the 204 and an extra pair of rods.
As much as I like the RES stones, I can't see ever using them again unless I have a large knife that's in really bad shape.
The diamond rods may seem expensive: the quality they give, along with the speed, make this a solid value.
It's been a long wait, but man it was worth it.
Does anyone know what the recommended way to clean them is? I'm hesitant to use a Scotchbrite pad on them.
