How the points were given
Each saw is scored on performance, build, value, safety and warranty, with the weights the site publishes on its How We Pick page. No listing here states a UL, ETL or CSA listing, so every saw scores zero on safety, and two give no clear warranty term.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| DEWALT DCS387P1 | 9.5 | 30 | 21 | 20 | 0 | 3 |
| BLACK+DECKER BLRS78E1 | 9.5 | 28 | 20 | 21 | 0 | 3 |

| SEESII 21V Saw Kit | 9.4 | 28 | 18 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
What the listings tell you
This guide covers four reciprocating saw listings. Three state a stroke length, two state a speed figure, two state cuts per charge and two state a warranty with a clear term. Three state a weight. Only one kit ships two batteries, and only one includes sanding sponges alongside the blades.
Buying guide: best cordless reciprocating saw dual battery kit
Batteries
Only the SEESII kit ships two batteries: two 4.0 Ah packs for 21V power. The DEWALT DCS387P1 ships a 5 Ah battery, the BLACK+DECKER ships a 2.5 Ah battery, and the DEWALT DCS384WW1 ships a battery with no stated capacity, so each of those three kits leaves the spare pack to the buyer. The 2Ah vs 5Ah 20V battery comparison shows how the two capacities differ.
Stroke length and speed
Stroke length is the distance the blade travels on each pass. The two DEWALT saws state a 1-1/8 in stroke, while the BLACK+DECKER states a 1 in stroke, and the SEESII listing states no stroke length. For speed, the SEESII title states 3500 SPM and the DEWALT DCS387P1 states 0-2900 SPM on a variable speed trigger; the BLACK+DECKER lists dual speed settings with no range, and the DEWALT DCS384WW1 states no speed at all.
Blade changes and blades
Blade changes are tool-free on the BLACK+DECKER and keyless on the DEWALT DCS384WW1, while the DEWALT DCS387P1 uses a 4-position blade clamp for flush cutting. The SEESII kit includes 6 blades and the BLACK+DECKER kit includes 3 blades, a 12 in wood blade, a 6 in wood blade and a 6 in metal blade, while neither DEWALT listing states a blade count.
Kit contents
The SEESII kit is the fullest box here: 6 blades, 24 sanding sponges, a fast charger, a carry bag, safety goggles and work gloves. The BLACK+DECKER kit adds three blades and a battery state-of-charge indicator, and both DEWALT kits include a battery and a charger. Check the blade count and the charger before the first job, since the listings differ on what is in the box.
Warranty
The BLACK+DECKER carries a 2 year limited warranty as standard, with 3 more years when registered within 30 days of purchase, and the DEWALT DCS387P1 carries a 3 year limited warranty. The DEWALT DCS384WW1 lists a Manufacturer Warranty with no term, and the SEESII listing states no warranty at all.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Space: the DEWALT DCS384WW1 measures 20.8 in long as listed, while the compact DEWALT DCS387P1 measures 14.5 in and fits between studs, so measure the space where the saw will live.
- Power: all four saws run on 20V or 21V batteries, and only the SEESII kit ships a spare pack, so keep the charger near the bench for the other three.
- Storage: the SEESII kit packs into a carry bag, while the other kits list no bag, so a shelf or a tool bag keeps the saw, blades and charger together.
- Before the first job, check the blade clamp and the blades in the box: the DEWALT DCS387P1 has a 4-position clamp for flush cutting, and the BLACK+DECKER kit includes a 12 in wood blade for long cuts.
- Weight: the BLACK+DECKER lists 5.909 lb and the DEWALT DCS387P1 lists 7.0 lb, while the DEWALT DCS384WW1 lists 15.55 lb, so pick the weight that suits work overhead.
FAQ: garage tools
What does a dual battery kit mean for a cordless reciprocating saw?
It means the kit ships with two batteries, so one can charge while the other cuts. Only the SEESII kit here ships two batteries; the other three kits ship a single battery each.
What stroke length should a cordless reciprocating saw have?
The two DEWALT saws here state a 1-1/8 in stroke and the BLACK+DECKER states a 1 in stroke, while the SEESII listing states no stroke length. A longer stroke covers more material on each pass, so match the stroke to the thickness of the work.
How many cuts per charge do these saws claim?
The BLACK+DECKER claims up to 33 cuts per charge and the DEWALT DCS384WW1 claims up to 102 cuts per charge, while the other two listings state no figure. The claims come from the makers, and the material and the blade change the result.
Do these kits include blades?
The SEESII kit includes 6 blades and the BLACK+DECKER kit includes 3 blades, a 12 in wood blade, a 6 in wood blade and a 6 in metal blade. Neither DEWALT listing states a blade count, so check the box contents before buying.
What warranty do these saws carry?
The BLACK+DECKER carries a 2 year limited warranty, plus 3 years with registration within 30 days of purchase, and the DEWALT DCS387P1 carries a 3 year limited warranty. The DEWALT DCS384WW1 lists a Manufacturer Warranty with no term, and the SEESII listing states no warranty at all.
