A strap wrench is any of various types of wrench that grip an object via a strap or chain being pulled in tension around it until it firmly grips. High static friction keeps it from slipping.

An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
Spike mauls are akin to sledge hammers, typically weighing from 8 to 12 pounds (4 to 5 kg) with handles 30 to 36 inches (80 to 90 cm) long. They have elongated double faced hardened steel heads.
