I am making a quilt for #2 son (51) and it takes 182 2" strips of one color and 288 of another. Yeah, he picked it out. So, I slip and took off the end of my nail. My husband suggested I stop for awhile and go to Harbor Freight with him. While there I bought 2 sizes of suction handles. Came home a started cutting again after about 40 cuts I slipped again sliced into my thumb but not badly. Husband is now laughing because tho I bought the handles I had not put them on. So, he installed on both rulers I am using. Lo, 200 cuts, not so tired and not once did my blade slip onto the ruler. I am a believer. Total cost $7.10
