Kaizen Foam Spinner

Works great for cutting foam layers.

Not bad takes a bit to get used to but keep them flat and the do a good job.

Spinner

Works so so, hard to control but useful to fix details. Have to be careful as it is deceptively sharp for plastic. I think that having it less sharp and adding teeth could be as or more effective without the risk of getting those nuisances paper cuts. I would buy it again as it is useful.
