I have been using a crinkle cutter for my soap logs without problem. I am noticing now that the soaps are bowed to the point they appear to be slightly curved. I thought it was the cutter box (wood) but have discovered it's the crinkle cutter itself which is now slightly bending in the center as I cut the bars. This cutter is heavy duty stainless steel made for cutting soap. It appears it may just be weakening from use. I have a dough scraper type that is cutting perfect bars and the difference is that one is way sturdier and solid, the wavy one is a 2" wide strip with a large opening between it and the handle which makes it flex- you all know what I mean, they all look alike. I like the wavy cuts but haven't been able to find an alternative type for that. Does anyone know of anything that would do the crinkle cuts without flexing or a remedy for my problem. I'm willing to upgrade to a better cutting system so hoping to get suggestions and recommendations here. Thanks!
