For over 10 years I had been on the hunt for a trimmer that can handle thick paper, that can cut perfectly straight, that does not have guidelines that wear off and that does not need to have its blade changed all the time. This trimmer has it all! The double bar keeps the cut perfectly straight. The blade runs underneath a protective housing so no worries about hurting your fingers. The blade is self sharpening and never needs to be changed. I have mine for a couple of years now and it still cuts perfectly straight through everything from vellum to thin chipboard! The guidelines are underneath protective clear plastic and do not wear off! I like that it folds in half for taking to crops and that it feels sturdy and solid. This trimmer is worth every penny.
Just received and used it. Have tried cutting multiple (4) layers of 120 lb cardstock, with unhappy results. Seems to have a difficult time cutting...jagged edges, bottom pieces of cardstock shifts and, therefore, end up crooked.
My best result was with one piece of cardstock. Although, blade seems to struggle through the cut.
Have not attempted any other media.
Would be nice to have an instruction sheet, as well.
This is a dream cutting machine. Thus far, it has given me smooth cuts for all all card & paper weights that I've tried. That includes No more rough-sawn edges to hand cut or sand away.
I've used the trimmer on medium weight chipboard, with the same results: professional, smooth, cut edges. I will say that it takes a bit more pressure to run the blade up or down against the heavier material, but if I can manage it, I think most others will also.
The double rod construct keeps everything level & steady, and even though I have severe hand and arm issues, I can easily operate the blade--either going up or coming down. Reviewers had warned that it might take extra push or pull to get the job done, but I'm having no problem.
A couple more of my favorite things about this Rotary Bypass Trimmer are:
1. the self-sharpening blade--don't ever have to change it.
2. the smaller footprint--folds in half and uses less storage space when idle.
I would absolutely recommend this wonderful product.
