Please note - Part 11486 is no longer available but our 4.25" three hole blade works nicely. The original Junior Tomahawk blade had two threaded holes while this replacement has the same dimensions and hole spacing but has counter sunk holes rather than threaded holes. To work on the Junior Tomahawk, the impeller assembly can be removed and the blade can be installed with the fasteners included. You will just use the two outside holes and the center hole will not be used.
