Hi, guys;
I currently use the silky zubat hand saw. I take a little time to clean it daily, as recommended by the manufacturer, before the start of the day. I usually brush off the loose saw dust and spray it wih WD40.
The tab on the pastic scabbard broke off mine also but I still prefer to use it instead of a leather scabbard. For me the plastic scabbard stays clean of saw dust and twigs more so than a leather scabbard.
It's also lighter but without the tab the scabbard will rotate and the saw will fall out of it.
The handle on the zubat is a soft, firm rubber and the replacement blades are made to fit deep into the rubber handle.
When the saw seemed dull and I felt it was time to replace the blade, it was still cutting more efficiently than other hand saws I've used. I think the way I take care of it may have something to do with it's extended performance. It's nicely balanced too.
I'm certain the silky zubat hand saw can be purchased through Sherrill Arborist supplies.
