Is it Worth it?

I have had my T7 for twenty years and as a professional sharpener I use it a lot. I was looking forward to trying this wheel and to see if it would take my knife sharpening to he next level. I was also interested to see if it would remove the need for stropping as claimed. I have never been a fan of the Tormek leather wheel and that hopeless cream that goes everywhere except on the wheel.

I used the stone with it turning towards the edge as usual and in 15 minutes I had had three dig ins and had taken lumps out of the wheel which was really annoying. It is going to take a long time to get those out. I was pressing reasonably hard, but no harder than usual. For some reason the stone caught the edge and threw the knife and jig towards me. I was forced to switch to trailing mode and that seems to be the best way to use it.

The wheel certainly removes metal efficiently albeit slower than the standard SG250 stone and it definitely does leaves a polished bevel. You will need to dress the wheel very regularly since it quickly becomes loaded with the steel from the knife. I would say that it gives a sharper edge than the standard stone and stropping, but not that much sharper and frankly I doubt whether the vast majority of my customers would notice the difference.

So is it worth it? Well I think you would really need a very good reason to need that extra degree of sharpness and it is an awful lot of money to achieve it. You can put a short, polished secondary bevel on most edges in other cheaper ways.
