With this tool as long as you do it smooth.You should be able to do the bulk of the cutting in 4 cuts.With a little bit of touch up.

Unlike the BD trim tool, the G3 tool is designed to make a straight cut that leaves just the edges exposed. No need to stress about wavering cuts or unequal trimming. Trimming your skins is simple with the G3 tool.

Is this only designed for G3 skins? It doesn't say so in the description. I used them on the first of my BD Ascension skins and it was a miserable experience.

The tab that lifts the skin stuck to the glue so badly that it was nearly impossible to push and gouged a jagged line down the skin that only barely followed the profile of the ski.

I used the included BD "paper cutter" tool to do my second skin. It was amazingly easy, made a perfect profile, and took half as long, even with the mandatory repositioning of the skin.

Eliminates the need to reposition skin to trim the other edge. Not sure how others have had problems. Make sure to trim from tip to tail or you will be fighting the entire cut. Used this tool for my first time cutting my own skins. Worked great on the BD Ascension STS. Well worth the $4.
P.S. G3 also has a great Twin tip Connector Kit that is compatible with the BD STS skin.

Great tool, sure makes trimming your skins much easier...A few touch ups after..and you are good to go!

Trimming my new Alpinist skins was unbelievably easy with the trimmer. It left enough space for the big edges of my pow skis, and cut through like warm butter.

I highly recommend this trimmer.

This is hands down the best skin cutting tool around. Although not rocket science, cutting usually requires moving the skins around on the ski and guessing how much to cut off for optimal edge exposure, other skin cutters can leave you feeling robbed after realizing your entire skin is crookedly cut. This handy tool allows you to center the uncut skins on the ski and make a straight forward cut.

Almost idiot proof. I'd cut BD skins before and there was the effort to set the skin slightly offset each side to trim the right amount off. With the G3 tool you simply put the skins on the center of the ski and run it down the edges. It's set to cut the appropriate distance in to clear the edges.

I've used the G3 tool for 3 pairs of skins now. I've used the traditional type tool that BD supplies, and which G3 also to used to include, for I think 5 pairs of skins.

Hands down - the G3 tool rules. I can trim skins perfectly in just a few minutes with the G3 tool. With the traditional old crude tool I've had a few screw ups and my skins were never cut anywhere close to "perfect" before, plus it was a dreaded task previously.

Best 4 bucks i have ever spent! Rather than using the stupid envelope cutter that comes with every other skin, this thing totally rocks and makes my life better.

This thing is a cinch to use. Buy a couple (like your shaver, it dulls slightly with each use) and have your buddies pay you to cut their skins. Perfect results with no practice. It's sized to leave your base edge plus just a few millimeters of ptex showing so edging and side-hilling are no problem-o. Mine came with my G3 Alpinist skins. I used it to cut mine and then cleaned up my roomies BD Ascensions. Still sharp enough for another job, but I'm looking to grab another just to be on the safe side.

Used it with BD Ascension skins and climbingskinsdirect.com skins and it worked perfectly.
