NT Professional Mat Cutter, 45 Degree Bevel Mat Board Cutter, 1 Cutter (MAT-45P), Aluminum Die-Cast Grip, Red/Grey

Works well. Easy to use if you comprehend the concepts. It cuts at an angle with an angled blade. If you carefully follow the instructions you will end up with a perfectly cut mat the first time. Adjustable in many ways, great value.

The unit is well built and sturdy, there is a learning curve to using it effectively. Be careful when you first use it, the blade is very sharp. The blade is inside the unit but emerges as soon as you press the large knob. The depth of cut scale on the blade sleave is not very accurate, so several test cuts on waste material are required to get the correct depth.

Love this mat cutter. Needed a couple mats for some pictures around the house. Local craft store was fairly pricey on them cutting them. Was able to purchase the matting boards and cut them myself. Very easy and simple to use. Highly recommend.

Pretty tricky to use. Going to take practice. The marks on the sides do help you with lining up. But there’s no way to really measure where to place it so it cuts at exactly the right place. You have to start slow and eye ball it. It’s fine for infrequent use and if you have a lot of time and patience. If I could have afforded I would have bought a higher quality one with a guide edge.

I didn't want to pay for framing a print - it seemed silly because I had the frame and just needed the right size matte (the print was an odd size so precuts didn't work). I bought a big matte and practiced on a piece about 8x8 until I felt confident to do the deed. It worked great and my picture is framed & looks wonderful! An artist friend gave it his approval when he visited recently. As an art lover who likes to pick up frames at thrift stores, this cutter will get plenty of use!

I do not recommend this product because it is very uncomfortable to cut. The cutting side is a face of the matt and it leaves dents because the bottom is not flat. The second bad thing is it moves in different directions and it is very hard to control. The third one is the mark where to stop or start is very broad and makes angles cut too far or not cut enough. The design is very poor. Sorry guys! Very disappointed.

Needed to modify a purchased framed mat to fit my daughter’s 30cmx40cm diamond painting. Didn’t want to pay a fortune to have it matted and figured I won’t need a mat cutter many times in my life so I went with this option over professionally framing or an expensive tool. I drew the necessary cut lines on back of mat with pencil. Laid down a cutting mat, my purchased mat, and then a heavy metal ruler. After determining where the ruler needed to be placed, I clamped the ruler down to my kitchen island so that my pencil lines were between the visible area of the tool. Pressed down on tool to confirm the blade hit the mat on the line. Used screw adjustment to adjust the blade to the necessary depth and pressed down and toward mat as I cut. I didn’t practice and it did wander a bit (more when I tried to push down with two hands than when I used one to steady the myself and one to do the cut) but it isn’t noticeable from my finished work. Worked as I expected and am happy to be able to frame the non-US standard 30cmx40cm diamond paintings my daughter has taken a liking to.

The base of the cutter is curved, so you need to concentrate on keeping even pressure centered on the hand knob. If you rock forward or back, it will cut crooked. Once you master that, it can do some nice work. I matted 12 pieces of art in various sizes. I started with the smaller mats first and it gave me the practice needed before moving to the large pieces.
