Review on Amana Tool Carbide Tipped Template Cutting Tools by Richard Sallah

I used it to cut grooves. He did a great job with knotty white oak using a plunge router and a 1/2" thick MDF template. I started the groove with a template, then since the oak was thick I removed the template and ran the stock over the ones before cut section. After that I leveled the corners with a chisel. Note that you don't need/need a long length of cut for this process as you will need to make some shallow cuts.
