Woodman's Pal Premium with Leather Grip & Steel Knuckleguard. Provides great momentum and fine balance. Recommended for all around cutting and chopping of brush up to 3 inch diameter.
The blade is SAE1075 cold rolled spring steel, hardened to Rockwell C47. A lower-carbon steel would not hold the edge for long. Harder steel (like SAE1095 used in fine cutlery) can become brittle in cold weather and can crack or chip with heavy use.
