I tried my Bolme Craft Knife yesterday. It's ergonomic and feels good in the hand. That's all that's good about it. Honestly this is something I'd expect from the altered mind of Tim Holtz rather than Ingvild Bolme. It's a total disaster.
First, I'm amazed that I still have fingers. The knife works beautifully unless you get adventurous enough to check out or change the other blades. There are 3 different styled blades in the base of the knife. Each looks valuable for different cutting jobs but refills are only available for the traditional crafting blade--at least at scrapbook.com.
Suppose you want to use one of the other blades. Then the nightmare starts. Try to change a blade. There are 3 internal mechanisms holding the craft blade once you figure out how to open the upper part of the knife. You have to handle the blade base and the knife base to twist the screw opening (where the blade is held) far enough to remove the blade (opportunity for amputation #1). This screw mechanism sits in a second screw mechanism for some reason and once the top screw is loosened the whole thing falls apart. Look on the floor for that is where the pieces holding the knife blade, and your blades, will be.
So you've freed your blade. Try to reverse the process. I still don't have it right I think. The new blade goes in the slits in the sides of the top two screws, which then go back into the bottom hole. You then tighten the two pieces and, voila, the knife is ready to go again. Opportunity for amputation #2: handling the new blade while trying to thread it into the slits in the upper screw hole. Opportunity for amputation #3: turning the blade to tighten the upper screw hole. Opportunity for amputation #4: Turning the upper screw hole into the second screw hole (while matching up the blade lines at the bottom). Opportunity #5 for amputation (this takes work): placing the top part of the knife into the bottom part and twisting to close.
About closing: there is a arrow on the upper part and lower part of the knife that indicates when the knife is "closed." At that point, it's pretty tight. But not tight enough. A simple movement will knock the arrows out of position and loosen all the mechanisms and you may have a loose blade again. Or you may simply have to align the two errors. Whichever, this happens frequently and is completely annoying.
I wish I had never purchased this dangerous little dagger that doesn't even come with instructions for changing blades though doing so is quite hazardous.
PROCEED WITH CAUTION. COMFORT MAY COST YOU FINGERS!! (LOL)
PS If you need to place your coins somewhere, Bolme's distressing tool is pretty darn sweet!
