Review on Enhanced CTA Tools A311 Feeler Gauge with 25 Blades by Lamar Vanderburg

Very oily when they arrived. Put them on my bench and I'll get a nice oil stain on my tree. I had to loosen the screw, remove each probe and wipe them with a paper towel. Good for transport and protection, but not very good for woodworking. I have some doubts about the accuracy of the probes. I used my digital calipers to test them and some of them were accurate and others were a little off. I've tried several combinations of blades to get a decent thickness and sometimes tricked the caliper into thinking the pin is folded and others not so much. Smaller needles in particular (less than 0.01 inch) feel a little off.
