拉花鋸片 46 TPI（1.50 x 5.50）

The hardened steel teeth on this 46-tpi blade slice through balsa like butter—the serrated edge leaves a surprisingly clean cut. It’s been a perfect fit for my K5 handle, and the soft metal backer adds just enough flexibility for precise pulls.

Finally found a blade that doesn't shred balsa wood on the pull stroke. The serrated edge is incredibly fine, and the soft metal backer keeps it rigid enough for clean, precise cuts. It's a bit thin at .012 inches, so you have to keep the handle steady, but the results are worth it.

The 46 teeth per inch cut through some tough fiberglass I had lying around much cleaner than I expected. It’s rigid enough for precise work but the soft metal backer helped avoid chatter.
