Which do you use and why?
I didn't even know replacement strips existed. I've replaced a red DMT with a Moonflex, but generally when I get a replacement it just gets added to the series based on my assessment of its condition vs others. I think I'm up to six stones now!
True. Diamond files are just lightly dragged over the edge giving final sharpness. When using them this way, they last for long time. I'm pretty sure I still do more skis then majority of people, and my diamond files easily last 3 to 4 years.Most important thing to remember when using any diamond file is that they are not meant to be a replacement for a file. Diamond files are for touching up and putting that sharpness back on an edge. When I hear about people wearing out diamond files on a regular basis, it's nearly always because they are using them wrong and or are applying to much down pressure which will just wear them out a lot faster.
