IMHO most of us retain the handle that came with the tool or substitute a cold hard pricy aluminum weapon for it because of pride in owning a touted brand name commercial product with its logo prominently stamped on the shiney (slippery) handle that bears little relationship to the anatomy of the human hand. (I have pride of long sentences) :)
Most of us probably agree with Reed that a plain and simple robust tubular wooden handle is best, but pride goeth before another "Stupid mistake" so we show off our store bought handled tools while mostly using our beloved and much preferred home made atrocity.
I reckon a lot of us actually bask in reverse 'pride of handle' with the dirtiest, longest, most scarred, paint stained, glue encrusted, unferruled mess being our favorite.
