I'm still waiting for mine to arrive but I'd like to hear some feedback on these two stones. I'd like to hear about scratch patterns, cutting speed, maintenance, edge quality... Did they replace some of your other stones? What types of steel are you sharpening? I'm moving to a completely splash and go set up and have high expectations for these. TKS MB
I've been really happy with them. I've only used them about six or seven times so I was waiting to get more time with them before going more in-depth.
As far as stones go, like you I've gone to a harder, faster cutting, splash & go setup. I still keep some soaking but instead of taking my time and playing around in mud like before, I'm looking to just get down to business with my edges.
I find them to both cut extremely quick. The 1k in particular seems super aggressive, but I'm not sure if that is also because of just how it sounds while you're sharpening on it. The first knife I tried on it was a Hiromoto AS, where the edge had been practically dialed in & I've sharpened it tons in the past. I raised a huge burr on it within a minute... surprised me. That's the only carbon I've used on the stones but I've found the Hiromoto AS to be kinda finicky on certain stones in the past... so I imagine a White or Blue would react really well. I've sharpened SG2 & VG10 and they sharpen up super quick too.
Feel & feedback is similar to the Shapton line of stones (which they're replacing for me). The 6k feels a lot better, naturally, and as a 1-2 punch I find it quicker than any other combo I've tried. At least at that high grit range (I also have a JNS 6k & Rika 5k).
I haven't finished any knives directly on the 1k. I'm going to try that next. From just feeling the edge while sharpening it seems super aggressive and I've been really interested in the 6k. I like the end result that I get off the 6k - a nice mix of tooth & refinement - even though I personally prefer a more coarse edge n my knives. I'm also going to try just stropping a few times on the 6k and seeing how that does me.
The included stone holder is a nice benefit but I don't personally need it. I've got your pretty standard stone holder and these stones are more than tall enough with their bases. They're about double the height of a Shapton GS and fair bit taller than Shapton Pro's.
They do leave pretty deep, bright scratches on knives. They have that in common with other diamond stones. I could see that being the main negative about these for some people. If you like to start behind the edge and work your way down when you sharpen, and are a little particular about the finish of your knives... these might not be for you.
They do seem to load up a little bit as well. The 6k in particular. Nothing terrible - it's another thing that I find similar to Shapton Glass Stones - but I am glad the nagura's were included. That said, I haven't yet seen it really effect performance and I haven't needed to use the nagura.
Overall, I find them to be like Shapton GS on steroids. Which for me is a positive - because after playing around with a fair number of different stones, for the past few months my Shapton GS 1k was seeing about 90% of the action out of all of them. (The only other Glass Stones I've owned/used was a 4k - which I thought was absolutely terrible and probably my most regretted purchase. The 6k diamond blows that out of the water).
