Weishidai Cutter 45 & 90 Degree Bevel Mat Board Cutter, with 3pcs Free Replacement Blade (Green)

I ended up being happy with this purchase, but there is definitely a learning curve to using it. I originally placed my cutter on a sewing cutting mat. This is usually a great idea, but in this case it was not. The blade needs something to sink into. A piece of cardboard without creases works well... at creases it is easy to get a crooked cut. The straight cut requires a low profile straight edge because the blade button sticks out pretty far and goes down close to the mat. I used a higher straight edge on the beveled cut than i did on the straight cut. I also clamped my work down to the table so that it would not move...this proved to be a priceless idea because it is pretty easy to get a crooked cut (as with any small simple cutting device). Overall I am very pleased. I practiced a lot before doing my beveled cut for my matting... word of warning: be very careful in the corners. If you need to cut more pin it down again; dont attempt freehand small cuts.

This mat cutter is a piece of junk. Very difficult to see where the blade will plunge into the mat board and the blade wanders, making a wavy cut. I tried to make several super light passes in an attempt to keep the blade from flexing, but it was no use. Would not recommend this cutter.

I got this small version because of the price and because I was just going to do a few pictures. But is much harder to use than I thought. You have to use it free hand or with a ruler. The cut is offset so the chances of getting the cut in the right place is about 50/50 at best. That means a lot of expensive wasted matte board. Not to mention the frustration [well, I just mentioned it.] This cutter might be good for a big table with board clamps, but if I had that space I would have bought a big cutter. I think this item might be good for someone who is set up to use it. But for the part time user, NO.

this is a piece of crap...the 90 degree blade does not hold true and your cuts will show it as a line that looks as if you cut it with an exacto knife freehand after drinking a 12 pack in 30 minutes. if that doesn't make sense, try my example and see what you come out with. avoid at all costs. this item probably cost 13 cents to manufacture and I paid over 20 dollars. learn from my mistake and look for a metal housing or maybe even an American made item?

Easy enough to use - just make sure you practice a lot before doing the real thing. You really have to make sure the straight edge of the cutter stays against your straight edge. It's easy to get going fast and have it veer away from the straight edge. Great price for the product. Saves you a ton of money instead of paying for a custom mat at Michael's or some place similar.

I got this to make it easier to cut matting for picture frames. I like that it's simple to cut either 90° or 45° angles simply by turning the tool around. Be careful though, it's very easy to accidentally remove the blades by pulling them up to much. (You need to pull the blades up a bit so that the one your not using at the moment doesn't cut where you don't want it to.)

Don’t bother with it.

Both 45° and 90° blades slightly move to the inside of holder because there's a small gap between the blade and the holder, and as it cuts the blade bends toward the inside against the holder. This does not allows a straight cut. To avoid the issue, i have to place something small and strong in that gap, and even so, if not aware the blade will bent and ruin the cut.
