MartelliLeft Handed 45mm Ergonomic Fabric Rotary Cutter - sewing, quilting, fashion design - designed for safe pain free fabric cutting - great if you have arthritis or carpal tunnel

This is by far the best rotary cutter I've ever used. With the standard "vertical" cutters, even with a sharp blade, I feel my wrist rebels at the pressure imparted while cutting. With the Martinelli cutter, I use no undue force to my cut because it's ergonomically designed to not stress the wrists, keeping them in a natural position. I have both a right-handed, and a left-handed model, and I can switch easily from one to the other without thinking about it. I can, and do, even sit while cutting. What joy! It's to bad this cutter is not the standard, and that all the major sewing outlets have only the normal Fiskers or Westcott, etc. Those are poor designs.

I use these rotary cutters whenever I am working on cutting out fabric using a sewing pattern, as well as for cutting strips or other shapes for making piece items such as quilts. I have some naturally-occurring arthritis in my hands but Martelli cutters make working on projects so much easier. I also use their blades exclusively. Both are a win-win in my opinion.

I have nerve damage in my dominant hand. It curls and cramps but with this cuter I can still cut. Freeing.

I am left handed and this is easier for me to use because of the ergonomic design that helps with my tendonitis.

It is hard to find left handed items. Works great 👍

This is the best - what a fabulous design! I am so glad it was recommended to me as it is so much better than a traditional style cutter. You do need to be careful to hold it as instructed or I think it could be easy to cut yourself. There is a small black (rubber??) piece that falls out of the blade protector when I close it. I'm not sure what is the purpose of this piece, as the blade protector is fully functional without it, so I just keep replacing the piece and am considering adding a spot of glue. Again, totally not important to either function or safety that I can tell. I cannot get the blade unscrewed to replace it, but will try a pair of pliers which I am sure will work.

Just works lefty and only Away from you

I've been using and loving my same rotary for 20+ years. Now I have arthritis in many of my joints and I had to change cutters. This Martelli cutter is a game changer for me. My hand and wrist are in a straight line and I use less pressure in my grip. My shoulder seems more relaxed. I can sit while cutting/trimming. I am so happy with my new Martelli.

Far more comfortable for this southpaw than the “universal” fit of a straight handle rotary cutter. Takes a bit of practice to cut straight over a longer distance, but well worth the effort, and the blades are SHARP!

Have used one of these for years and never needed to change blade, even cutting off jeans hems for my at the time, alteration business, 6+ years ago, now comes time to change blade, but thought I would buy a new cutter, have one for vinyl, bagmaking, and one for patchwork. Best cutters ever and I will tell anyone that wants to listen, :) or not, but best ever.

I really like my left handed martelli cutter. I had a hard time cutting with it until I watched the video on how to properly use it. It works much better than my friskars cutter and will cut through multiple layers of material with ease. It is also very comfortable to hold.

I do like this rotary cutter because it fit in your hand and so lite I find it that no strain on your hand I love it

Everything wonderful
