## Product: C.S. Osborne Rosette Punch 139 (1-1/2")
**Brand:** C.S. Osborne

The C.S. Osborne Rosette Punch #139, measuring 1-1/2 inches, seems to be a hit among leather enthusiasts for its ability to create neat, round shapes. Right out of the box, it's recognized for being pretty sharp and precise, which is what you'd expect since its edges are CNC machined, according to the manufacturer's description.

Based on what we've found, people generally think it's efficient. One person mentioned switching from a less well-known brand of punch that needed several hits to cut cleanly, to the Osborne punch, which just needed one steady tap, especially on materials like [Cordura](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dcordura%26tag%3Dssw.ans.tx-1-20) (similar to canvas). 

This highlights how easy it is to work with lighter materials, saving both time and effort.

That being said, when it comes to thicker or tougher leathers, some folks have found that it might need a bit of a touch-up or sharpening first. One person shared that after giving theirs a quick sharpening, it worked just fine even on [Horween leather](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dhorween%2Bleather%26tag%3Dssw.ans.tx-1-20), which is pretty tough stuff.

Overall, it seems like the punch does a great job right from the start for lighter leather projects. Just a little bit of an adjustment might be needed if you're working with the thicker stuff. 

So, if you're into making detailed leather creations, this punch could be a handy tool to have around.
