Oshkosh Straight Shovels are made with Ash hardwood handles and special 10-inch carbon steel blades with boron. The blade is forged to our special straight pattern and is then heat-treated . The straps are electrically seam welded to the blade. This shovel is completely straight from end to end. We also offer this straight shovel with a 6-inch blade. Handles are marked with footage marks to indicate the 3, 4, and 5 foot depth of hole.
