Hm - I am superlazy and have no idea about sharpening. I just wanted something that works and spent a considerable amount of time researching so that I do not have to spend a lot of time for sharpening, lol!!
I bought the v-sharp XE with 3 different diamond stones for solingen kitchen knives. I did not want to buy a machine because the grindstones / sandpapers for these machines tend to be very expensive.
By using the 3 stones and then the steel (on the other side of the sharpening thingie), I can make them so sharp with the v-sharp xe that they cut telephone book paper very well. So far I sharpened 50 or 60 knives. Takes about 3 or 4 minutes per knife to get it to telephone book sharpness (3 stones and steel, of course you put 50 or 60 knives through one stone and THEN switch to the next stone and the next stone and then the steel :-D), or 1 to 2 minutes each for kitchen sharpness (only coarse stone with or without steel, steel does not really seem to matter a lot for "kitchen sharpness", but is good for touch up). Most knives were really dull.
I think telephone book sharp is not razor sharp, right?
But sharp enough I guess

.
BTW according to the v-sharp guys you should not make kitchen knifes so sharp, you should just use the "coarse" stone because the knife will then cut kitchen things like tomatos better

(because the edge will be more like a sawtooth instead of completely smooth or something)
Can I use the v-sharp xe for the plain cold steel voyagers that I have? (did not need to resharpen them yet)
Can I use the v-sharp xe for the new cold steel finn wolf with this scandi grind, whatever this is?
I also have a transport case for the v-sharp xe, very nice. The v-sharp xe is very lightweight. Not very handy perhaps.
If you want an emergency sharpener for outdoor use, I heard the vulcanus pocket is "good" (I mean, it is a hard metal sharpener, but probably the best "hard metal sharpener". Puts an edge on superfast and can even sharpen serrations...my parents use the "regular version" a lot. Oh and I think its Vulkanus with K. Like the Men in Black K. lol
I dont use it because the v-sharp xe is "lighter" on the knives because it has diamond stones and also very fast!)
Oh and I dont know how long the v-sharp xes diamond rods will last until they wear out, so far they seem to hold up well after 50 or 60 kitchen knives!
Thanks!!!
Someone some number I forgot <--- lol from Europe
