A pipe wrench (210, 310) including: a head (214, 314) including an aperture (270, 230), the aperture having a front wall (72, 172) and a back wall (74, 174); a first jaw (228, 328) that is fixed to the head (214, 314), the first jaw including a plurality of teeth (232, 332) that define a contact region (236, 336); a second jaw (230, 330) that extends through the aperture (270, 370) of the head (214, 314), the second jaw (230, 330) including a threaded portion (254, 354) and a plurality of teeth (234, 334) that define a contact region (238, 338); a floating mechanism (78, 178, 278, 378) disposed in the aperture, the floating mechanism supporting the second jaw in a central position within the aperture, the floating mechanism comprising: a first resilient portion (82, 182, 282, 382) disposed between the front wall of the aperture in the head and the threaded portion of the second jaw; a second resilient portion (183, 283, 383) disposed between the back wall of the aperture in the head and the threaded portion of the second jaw; and a web connecting the first resilient portion to the second resilient portion; a thumb wheel (252, 352) that includes threads (258, 358) engaged with the threaded portion (254, 354) of the second jaw (230, 330) such that rotation of the thumb wheel (252, 352) relative to the head (214, 314) moves the contact region (238, 338) of the second jaw (230, 330) toward or away from the contact region (236, 336) of the first jaw (228, 328); characterized in that it also includes a bore (213, 321) in the head, including a first end, an opening opposite the first end, and a threaded portion positioned at the first end; and an extension handle at least partially received in the bore (213, 321) through the opening before the extension handle engages the threaded portion of the bore (213, 321) at the first end, the extension handle being removably coupled to the head (214, 314); wherein: the head includes a second aperture that extends transversely into the bore and is configured to allow a user to determine if the extension handle is coupled to the head; and/or the extension handle includes a proximal end portion and a distal end portion, the distal end portion received at least partially within the bore, and wherein the proximal end portion includes a second bore configured to receive an extension handle. a head (214, 314) including an aperture (270, 230), the aperture having a front wall (72, 172) and a back wall (74, 174);
