Drag knife cutting tool

thingiverse

I got one of these "Swivel cutters" and was disappointed with the handling. So i took a spare knife holder from our foil cutter and "designed" some kind of holding attachement in tinkercad. The most important thing while using this is that the knife has to be perpendicular to the cutting surface and for me this knob thing works much better than the pencil style holder the bought one uses. Of course it may have to be adjusted to different hand sizes and i just glued the knife holder in, a clamping mechanism with a screw might be better if you want to be able to take out the knife holder. These knife holders for roland cutting machines and also spare blades are plentifull and cheap in these chinese shopping websites and work much better than the blades the swivel cutter comes with, since there its only a sharpened bit of square steel bar. On the other hand i guess it would me much easier to resharpen the steel bar, if a cutting knfe wears out, you have to use a new one. and it is very important that the knife is as sharp as possible, especially if you want to cut paper... Anyways, thas my idea and im curious if someone picks it up and builds upon this....
