Question: I can't get regular reciprocating saw blades to work?  Are there special blades for this saw?
Document: This is my first reciprocating saw, so I have nothing to compare it to. The saw comes with a wood blade, an instruction booklet and a product registration form.I have a few tools in the Black and Decker 20V max family, so I have 4 20V batteries.
I have been looking for a 20V lithium battery reciprocating saw to go with my drill and weed eater. I finally found it on Amazon. I wanted it to prune the lower limbs off of my oak trees and this saw did the job., also I am Able  to use the batteries from my 20V system to run each of  my other tools. This was a great buy for my overall purposes.
Over a year ago, I bought a B&D 20V Max drill/driver, which has become indispensable. The 20V battery pack seems to last &#34;forever.&#34;  Based on this experience, I set about replacing my old Sears 19.8V tool set with Black & Decker 20V Max tools. (The Sears batteries were no longer capable of retaining a charge long enough to be useful.) The BDCR20B reciprocating saw is a new addition to the 20V Max family.
I needed something lighter than other battery powered recip saws for work in the garden. My hands and strength are failing me. This is ideal for removing branches too large for loppers. Obviously the blade is too small for anything much larger than 2 inches, but just right for about 90% of my needs. Battery lasts longer than I do, maybe an hour of off and on use. Also have the 20V Max Lithium grass trimmer. Keeps me in the garden.
I  used this saw yesterday with a Skil pruning saw blade and it easily cut through some unwanted saplings. If I have any different experiences I will post an update to this review.
Yet 1 more great tool from Black & Decker. I already have many other of the 20 Volt tools along with many batteries. The saw just simply works very well. The tool free and easy blade change is great!
And unlike the old recip saw, I don't have to stop every half hour to replace the battery pack. My new 20V Max tool set also includes the circular saw (also reviewed) and the edger/trimmer. I will continue to rely on Black & Decker for more 20V Max tools!
I used this saw to cut landscape timbers (3x4x8 in size), and had about 12 cuts. It had no issues; when used properly, the cut turned out clean and straight. The saw felt comfortable in my hands.After the project, I also trimmed a branch (2 inches in diameter). No issues at all. I will trim several more next weekend.
I bought this saw for cutting plastic piping and 2x4s, It works great, it's lightweight and cuts through most materials with ease. Black & Decker makes quality products that continue to impress me. However, I'm giving this product 3 stars because it does not come with any power supply. I did not realize bare referred to no battery or charger included. It is a great saw if you've already got a lithium battery.
This is the best tool I have bought in the last ten years. I recommend this for anybody who has wood to cut.
