发明名称 FIRE FIGHTERS' HATCHET
摘要 <p>A lightweight hatchet for use by firefighters and rescue workers is disclosed. The hatchet includes a head (11) having a blade side (15) and a cutting side (17), both designed to rip and tear an obstruction, such as a roof, wall, door, etc., without becoming entangled in the obstruction. The blade (15) includes a blade having a beveled edge (23) with a relatively sharp radius of curvature that ends at rounded corners (25). The rounded corners (25) terminate at curve-back regions (27) that curve back toward the handle (13) of the hatchet. The cutting side (17) includes a pair of teeth (31, 33), one positioned outside the other. The outside tooth (31) is curved and its periphery is beveled to create a cutting edge. The slot (35) between the teeth (31, 33) is shaped such that sheets of metal and other strong materials can be cut by inserting the outer tooth (31) in a hole in the sheet and ratcheting the handle back and forth. Both the blade and cutting sides (15, 17) of the hatchet head (11) are relatively thin. Further, the blade and cutting sides (15, 17) are of substantially the same weight to balance the hatchet.</p>
