Figure 2. Sharpening Reference Line
Sharpen the TSB using the sharpening fixture shown in Figure 3. Insert the TSB into the sharpening fixture and place the sharpening fixture on the 180-120 grit abrasive paper that has been positioned on a on a flat surface. Slide the TSB into the sharpening fixture until the blade makes contact with the abrasive paper as shown in the top right view in Figure 3. With the TSB held firmly in contact with the abrasive paper, roll the sharpening fixture back and forth across the abrasive paper. Alternate between the top and bottom side of the TSB when sharpening until the cutting edge has been restored and is aligned with the reference line shown in Figure 2. NOTE: Repeat the sharping process as necessary to maintain a sharp cutting edge during the material process.
