Ok, i have a new coticule but i'm having the same trouble. This one is a 6X2, i also have a 4X2. The small one was my first one and i had trouble with the tip of the razor not being sharp. Thinking it was because i didn't have enough surface to complete my half X stroke (Unicot) i bought a bigger hone. But as usual, it is me and not the equipment. I do the 30 Half X strokes just like Barts video until it shaves arm hair, from the tip to about a third of the way down the razor doesn't shave arm hair but from the top third to the heel it does shave arm hair, i switch to the 30 X stokes then and complete the unicot method. Should I continue doing the first step until the whole razor shaves arm hair or am i doing something else wrong? Let me say again. I do the half X strokes until the razor shaves arm hair (not the whole razor just about the middle to the heel) then i move to the next step. I end up with a razor that pops arm hair from the middle to the heel but doesn't do a whole lot of shaving from the point to about a third of the way down the razor. Any idea what i'm doing wrong?
