An Insider's Guide to Sharpening a Round Knife and Maintenance
As a beginner leatherworker, it's invaluable to learn how to strop your round knife. Regularly stropping with a knife will help maintain an already sharp edge and help keep your leather knife in good condition. A good rule of thumb is to consistently strop your leather working tools including leather round knives and leather head knives to ensure your tool will perform well with every leather project.
2. How to Strop Your Leather Round Knife with a Leather Strop Board
While there are reasonably-priced sharpening systems that make quick work of sharpening leather working tools including round knives, it's understandable that leathercrafters new to the hobby may want to start with a lower-priced alternative. That's where the leather strop board comes in:
Repeat the process on the opposite side for a smooth, polished edge on your round knife. Helpful Note: Sharpening is required less frequently when you regularly strop blade. If you don't have a leather strop board and aren't ready to invest in one yet, you can make your own strop with a piece of scrap leather attached to wood you may already have readily available. What's the best leather for sharpening round knives? We recommend natural veg tan leather if you decide to make your own stop board.
3. When Should I Upgrade to a Smith's Tri-Hone for Sharpening my Leather Round Knife?
For many leathercrafters out there, if you purchased a round knife that was professionally sharpened, stropping it before every use with a leather strop board using the instructions above will help maintain your round knife's edge. For those leatherworkers who really put their round knife through the paces, however, there may come a point when you want guidance on more advanced round knife sharpening techniques for knives that undergo heavy use or have not been maintained with consistent stropping. Our experts suggest investing in Smith's Tri-Hone, a leatherworking tool sharpening system that features sharpening stones in three grits for a variety of sharpening needs.
4. How to Sharpen Your Round Knife with Smiths Tri-Hone Sharpening System
You may wonder “what is the best sharpening stone?” Precision sharpening is easy with this sharpening system featuring a sharpening angle guide, honing oil, and three stones with different levels of grit:
Expert Tips: Our team recommends beginning with the Abrasive Sharpening Stone, working your round knife to achieve a sharpened edge. The Fine Sharpening Stone is used for final knife honing to achieve the ultimate polished edge.
Step 2 Maintaining the proper sharpening angle is key to achieving the sharpest edge. Our experts recommend a 15° angle for the best results. Smith's® Tri-Hone System comes with an angle guide that you can place at the end of your stone for guidance if necessary. Place your round knife's blade flat on the guide and you're ready for the sharpening process.
Step 3 Placing a slight amount of pressure on the back of the blade, sweep the rounded edge of the blade against the stone. When you start to feel the blade “grab” the stone, the blade is sharpening. Repeat this motion three or four times with your round knife. Important Note:Remember to maintain the same sharpening angle throughout the process to obtain the sharpest, best results.
Step 4 To sharpen the other side of your round knife, turn to the opposite side and repeat Steps 1-3. Continue sharpening until your blade reaches your desired level of sharpness.
Step 5 Rotate Smith's Tri-Hone to the Fine Natural Arkansas Stone and repeat the same process as above on both sides of the blade. Important Note: Never use a Natural Arkansas Stone without oil or water as this will damage and clog your stone. After each use, it's important to clean the stone to keep its porous surface clear from stone and metal particles. The Arkansas Stones can be cleaned by scrubbing with water, liquid soap, and a stiff nylon brush. Expert Recommendation:After using Smith's Tri-Hone Sharpening System to sharpen a round knife, our team likes to strop the newly-sharpened blade edge with our leather strop board and microfine honing compound using the method covered in the first video on this page. To keep your knife sharp and to extend the time needed between sharpenings, be sure to regularly strop your leather round knife.
