I just took advantage of the Joann sale and shipping! Whoo Whoo. Thanks!

I love the Martelli ErgoCutter. Have used it for several years now. It's the only rotary cutter I use unless I have to use a specialty rotary cutter. I have never tried the True Cut, so I can't give a opinion on that one, but, I love the ErgoCutter. Since you have arhritis in your hand, the Ergo Cutter is made for people who have problems with regular rotary cutters. You might want to give it a try.

Has anyone tried the EZ cutter ruler, all in one. After measuring the fabric with its ruler, just slide the attached plastic grip that has the blade underneath, and the fabric is cut. It's sold at Hancock's of Paducah and at present it's on back order and available in June. Some of my friends use it and swear by it. At one time it was sold at Walmart, but haven't seen it there in a while. I think Fiskars puts out a similar product. I hope this is a help for you.
Blessings,
