Brown & Sharpe #530 Knife Edge

Now we have a Brown & Sharpe Knife edge/straight edge in original box with green velvet lining in fine condition, has been used but appears to be in very good condition. If you have any questions I will do my best to answer them, but in all honesty I am not exactly sure what this is used for. Was found in a collection of my Grandfathers belongings and he owned a Tool & Die Shop.

Sold as is. Good Luck.
