Hi,
I have been using a guided sharpening system for a while, and I do a lot of reprofiling as I like low angle secondary bevel edges better.
So far, I was using a stock stone for reprofiling that came with my sharpening system, Suehiro 180 SiC, which removes metal extremely fast, but also dish very quickly. So quick that, it is quite easy to get an uneven surface in a few passes during the sharpening if not used the entire length of the stone. A a result of fast dishing this is a very messy stone capable of messing up entire work top. I have almost used up this stone, so I was in search for a similarly cutting stone with less dishing and with higher overall quality.
I ordered Venen Centaur 80 + 150 and Boride T2 150 as a replacement. However, neither of stones performed as expected. T2 150 seems to have very hard bonding and does not cut quickly at all. I spent 2 hours on a task which the same thing could be done with Suehiro 180Sic in 10-15 mins. It gives a better scracth pattern and it is not messy at all, but it is useless for my intendent purpose. Similarly, Venev Centaur did not perform as expected. It cuts faster than T2 150 but nowhere as fast as Suehire 180 eventhough the grit rating is far coarser. Despite not cutting as fast, that stone tend to leave deep scracth marks on steel. Additionally, it is not exactly edge pro format stone making its use a bit more delicate. Both of these stones lapped twice with loose SiC particles and been used on a quite few knives. So, they are suppoed to be in their optimal state by now. Since these stones are not performing as expected, I am in the market for replacement stones. I need a fast cutting stone with tolerable dishing speed, I do not know if it makes difference at that grit rating but I would prefer SiC as I plan to use it on PM steels as well. If it does not make a difference, AOx would be fine. I guess two stones with two different grits might be a good idea. My Chosera set starts from 400 grit and my resin bonded CBN set starts from 63/50 micron. So, I think the ideal stone should be something like 120 grit, and 220 grit can be considered as an optional stone when 120 is not mandatory. I was thinking of getting Boride CS-HD 120 and 220 but I am not too sure how they work. I would not mind getting a more expensive stone if it works great! I am quite happy with my Choseras that I wish they made lower grit ratings.
I would like to hear your opinions before making any other wrong purhase decision.
Thanks for all the help!
