I have ordered a set of two Dual-sided Venev Cerberus Dog stones to use with my KME sharpening system. As I use the stones, will I need to lap or dress them from time to time, to remove metal particles or to wear away resin bonding material in order to expose new diamonds? And what grade(s) of silicon carbide powder will I need, in order to lap or dress them?

You probably won't have to lap them unless they start to dish after many uses. You can remove the metal build up with a Scotch bright pad, magic eraser or nagura stone if they load up on you. The binder on resin stones slowly wears over time exposing new diamonds while you sharpen. When you do have to flatten them you can use grit that approximately half of the stone rated grit.

What’s your thoughts on using this Venev stone in 80+150 to reprofile knives? I’ve seen many reviews about this stone being great for finishing edges, but I’m looking for a great reprofiling stone. The reviews I’ve seen on YouTube (not always trustworthy) state this stone isn’t nearly as aggressive for reprofiling such as what you can get from the KME 150 grit. Thoughts…

A - Your best re-profiling hand stones will always be diamond plates. You can't beat them, and they are very inexpensive. They won't last forever and can't have their surface reconditioned over time but they are the best for re-profiling and chip repair jobs. Even just the cheap Chinese lower grit diamond plates work very well. After you've done the re-profiling work on a new or damaged knife, it's hard to beat Venev stones for finesse and speed of cutting. But yes, they are not designed to be re-profiling work horses. They'll do the job, but a diamond plate is certainly more aggressive due to the diamonds protruding much more from the surface of the plate.

You state in your description, “Cerberus is the first Venev dual-sided series compatible with KME knife sharpeners without having to use an aftermarket stone holder.”
But then in the below comments you say you must get a Leading Edge stone holder if using this Venev stone in your KME. Which is it?
Thx,
Mike

A - It is not designed for the KME stone holder but works ok in the KME holder
It will work much better in the Leading Edge stone holder, because that has been designed specifically for after market stones such as these.

You can use a little bit of Silicon carbide loose grit on a flat surface (like a tile, piece of granite, thick glass etc. Spray some water over the flat surface and sprinkle the silicon carbide over it. Then draw a cross hatch pattern lines with a pencil over your stone surface and slowly any methodically move it over the prepared surface in figure of 8 patterns until you remove all of the cross pattern lines from the stone surface and it's level again. Careful not to press down on one side of the stone more than the other side or you'll wear one corner down more than the others while leveling it. Also, it should go without saying but the surface you're using will be severely scratched by the silicon carbide so don't use a flat surface you care for.

Leveling should not be necessary for a very long time though, these stones wear down very slowly.

A - Yes the Venev Cerberus stones will work well but you'll need to get a Leading Edge KME stone holder (link below).

A good set of Cerberus stones would be the 80/150 ; 400/800 and 1200/1500 stone.

It would depend on what types of knives and what types of steel you want to sharpen. If you only have basic stainless or high carbon knives, then silicon carbide or aluminum oxide stones would work just fine. If you want to sharpen higher end knives with high vanadium carbide steels, then diamond or CBN based stones would work better. For great all-round stones, I typically recommend the dual sided Venev diamond bonded stones. Each Venev dual sided stone is effectively 2 stones, they are a combination of 2 grits (1 on each side)

If you only sharpen EDC type short blade knives of around 5 inches or less, then 4 inch long stones and a 4 inch Leading Edge stone holder is fine.

If you want to sharpen longer blades, then 6 inch stones and a 6 inch Leading Edge stone holder is better.

I also highly recommend a V block clamp support, the original clamp has too much play for exact accurate sharpening angles. The support block makes for rock solid sharpening with no play.

In addition to stones and a stone holder, I would highly recommend getting the Leading Edge universal upgrade kit (magnetic base, long blade and scissors attachment included.) This would open up a whole new world of possibilities for your Work Sharp precision adjust and allow you to sharpen just about any knife, and even scissors.

Hello,
Looking to buy this stone in 400+800. Is this equivalent to 1000 + 3000 grit?

Q - Looking to buy this stone in 400+800. Is this equivalent to 1000 + 3000 grit?

A - Venev uses the Fepa-F grit rating. Using the logarithmic grit conversion chart, when converted to the Japanese JIS R-6001 rating, the 400+800 would equate to approximately 700+2000. If converted to the Shapton Japanese rating, then then it would equate to approximately 900+2500

Below is a link to the logarithmic grit conversion chart for reference:

what stones to get

There is definitely no need to buy the entire series of stones. The grit combinations offer options that suit individual needs and preferences. If you don't have a set of these and want to purchase just 3 stones, then something in the line of 80+150 & 240+400 & 800+1200 would work very well. Another option would be 100+240 & 400+800 & 1200+1500.

If you just want 2 stones for every day use, then something along the lines of 100+240 and 400+800 would work well.

FYI, the grit rating used is "FEPA-F" on these stones, so an 800 grit stone is already a very fine and superb stone.
