Caliastro 9-Inch Wood Pruning Saw Blades for Reciprocating/Sawzall Saws - 5 Pack

Q: Will these blades work for cutting a railroad tie?

Yes. I have used blades like these on a corded recip saw to cut creosote treated oak ties. Buy the correct length for your ties. 9" is probably too short. Buy plenty, they will dull quickly. However, it beats the heck out of ruining a $400 chainsaw.

Q: do these blades fit the Skil 9 amp reciprocating saw?

Yes, the 9-inch wood pruning blades do fit all reciprocating saws including the Skil 9 Amp reciprocating saw.

Q: Will this work with Black and Decker saw?

I'm not familiar with how blades attach on a Black and Decker reciprocating saw however the attachment is very universal to 99.9 percent of saws so it's very likely that these blades will work great on your saw.
