## Abstract

A crowbar includes a handle, a blade and a reinforcement element. The handle includes a restraining portion. The blade extends from an end of the handle at an angle. The guiding and supporting portion extends from the primary blade at an angle and includes a tip connected to the restraining portion of the handle, thereby keeping the handle at a constant angle measured from the primary blade.

## Claims

A crowbar comprising:
a handle (12) comprising a restraining portion (42);
a primary blade (30) extending from an end of the handle (12) at an angle; and
a guiding and supporting portion (40) extending from the primary blade (30) at an angle and comprising a tip connected to the restraining portion (42) of the handle (12), thereby keeping the handle (12) at a constant angle (38) measured from the primary blade (30).

### Claim 2 (depends on 1)

The crowbar according to claim 1, wherein the restraining portion (42) is a groove made in the handle (12).

### Claim 3 (depends on 2)
