A utility knife/box cutter?

Should work on a lot of sidewalls, given a steady hand.   Don't expect to be able to cut Atomic cap skis or Volants with it tho.

Yeah, that's the one.  Most of my sidewalls are soft enough to cut, similar to the OP.

Basically if you go the cheap route, knife/chisel for plastic sidewall and file for fiberglass cap. Reason is if you do it the other way around a file can't file away the soft plastic, and a knife can splinter the fiberglass cap.

If you're using a file, why is a sidewall tool necessary at all? Isn't steel > plastic? Is it a big deal if the sidewall just continues the edge angle the steel ski edges get from filing? If you get some sidewall material in the file can't you just brush it out with a brass (tooth)brush?

 

What am I missing?

Speed.    The sidewall tool is there to save you time, time that would normally be spent filing plastic with a file designed for metal.   And cleaning that file.   And filing some more.  And cleaning. 

I mean think about it as an evolutionary process:
 

If you have a file that is almost wholly cutting plastic (and getting clogged with plastic), it would make sense to get a file better adapted to plastic, no?  

 But you can only get so close to the file being a rasp without actually  damaging the edges, so it makes sense to get a file that is jigged/guided to *only* cut plastic.

But then it makes financial and time sense to stop cutting plastic with  the multiple small cutting edges of files/rasps and  have your jig/guide support only one large cutting edge of a sidewall tool.

^^^^ Yes!

For those that don't do enough or at least on a regular basis any method that gives the desired results is also acceptable.

Good question.  The sidewall material above the metal edge varies in composition.  These compositions of plastics, fiberglass, carbon fiber, aluminum alloys etc. will clog the file designed for cutting steel.  Even then, only steel not too hard, such as a machined hardened edge.  You do need to clear above the edge to get at the edge.  Get one of the many tools to do that, and feel the difference.

You always need to clean the file anyway, so that's always good. 

 

So really you are missing a sidewall planer.

I always brush the file clean and wipe down the ski edges after every pass, max two. Probably will spring for a sidewall tool at some point, but used a narrow chisel today on a pair of skis, and then smoothed things down with sandpaper. Seemed to work pretty well - when I filed after that got very little if any sidewall material.

 

It's a relaxing pleasure to spend time with the skis, and show them some love. And it's always a kick to bring an old pair back from the dead and get them on the snow again. So far the experience on the hill has been good, so something's working.  ;-)

 

Cheers.
