I came across this device while searching for some tooling and thought it was kind of cool and wondered if anyone here has tried it out. It's a small magnifier that interfaces with your smart phone to analyze worn tooling, and it works with an app to access a database to determine the cause and type of wear and apparently has other features as well. If it works I can see it being useful especially on the shop floor for some of the guys to learn to identify tooling issues.
