The various media for sharpening in some cases have varying thicknesses and adjustments must be made in the degree settings.
When the WEPS was in its infancy, the cube was barely necessary, but with the addition of such things as the Chosera and Shapton stones for example, we run into variences that require compensating to get extreme accuracy in one’s edges. This also holds true for things like the balsa strops et al.
The recent rapid evolution of the WEPS has been crowded with additional tools and methods which those requiring sharpness in the extreme wanted/needed and the cube therefore has great value.I expect there will be many more surprising additions soon that will require even more delicate adjustments.
If one simply wants sharp, the standard package and setup is capable and the cube is not really necessary. I was turning out real-world sharp knives long before I acquired my cube.When I sharpen most of the time, I don’t even use the cube. It is only when I do one of my collection babies that I haul it out along with all my paddles and Chosera stones…and I put my paddle arms on in reverse for the finest accuracy plus a tiny squirt of Purple Loctite.
The learning curve for the WEPS grows a little steeper, while the edges it produces grow even beyond keen!
Leo…who should be in bed! Off I go! Hopefully the preceding makes sense.
