Black & Decker Craft Hobby Knife Kit with 26 Assorted Blades and Cutting Mat

I pulled the Black & Decker craft knife kit out of its case for a weekend of model-making and paper prototyping, expecting an all-in-one setup that could live on my desk without hogging space. After a few days of cutting card stock, trimming vinyl decals, and shaping thin balsa, I came away with a clear sense of where this kit excels, where it’s simply adequate, and how it fits into a hobbyist’s workflow.

Ergonomics and build

The handle is the heart of any craft knife, and this one is thoughtfully shaped. The contoured profile and over-molded grip distribute pressure well, especially during controlled, fingertip work. I never felt hot spots or the thumb fatigue that shows up with straight, skinny handles after long sessions. The blade clamp held tight with no wiggle or creep, even when I was prying tiny offcuts from chipboard—something I don’t recommend but inevitably do.

Overall, the handle leans more toward stability than ultra-fine nimbleness. It’s a touch thicker than classic hobby handles, which makes it steadier for scoring and straight-line cuts but a little less flickable for delicate, freehand curves. I liked it for long trims and repetitive scoring passes. For micro-carving foam or vinyl lettering, I slightly preferred a slimmer barrel, but the difference is small.

Blade assortment and swapping

You get an assortment of 26 blades, covering the common profiles for hobby work: fine points, curved edges, and small chisels. That mix handled everything I tried: precise vinyl weeding, beveling edges in thin foam, and clean pierce-and-drag cuts in card stock. The fine-point blades are sharp out of the box and hold an edge respectably on paper and light plastics. In soft wood (balsa and basswood), they dull faster—as expected—so plan to swap more often.

Changing blades is straightforward and secure. I had no issues with blades loosening mid-cut. What matters more is the right pairing of blade shape to task:

• Fine point for detail cuts and tight inside corners (paper, decals).
• Curved edge for long, smooth slices and paring motions (card stock, leather scraps, thin plastics).
• Chisel-style for light scoring, shallow mortises in foam, and shaving edges flush.

If you’re new to hobby knives, the profiles can look similar at first glance. I found it helpful to keep a small note in the case lid reminding me which shapes I prefer for which materials.

Cutting performance across materials

• Paper and card stock: Excellent. With a fresh fine-point blade, I consistently got crisp, feather-free edges. The handle’s grip helps maintain a steady angle across longer passes. Two light scoring passes worked better than one heavy cut for 110 lb card.
• Vinyl and masking film: Very good. The point tracks clean curves without pulling the material. The curved blade did best for peeling and trimming around contours.
• Foam board: Good with a sharp blade. The kit can produce clean, perpendicular edges if you respect pass count—three light cuts instead of trying to muscle through in one.
• Soft woods (balsa, basswood): Adequate. It’s fine for shaping and trimming small parts, but you’ll want frequent blade changes to avoid compression and tear-out. For rip cuts or deep shaping, a razor saw or micro-plane is better.
• Thin plastics (styrene up to ~1 mm): Good for scoring and snapping. For through-cuts, go slow and keep the blade cool; melting can drag the edge.

Edge retention is in line with standard carbon-steel hobby blades. If you primarily cut abrasive materials (chipboard, dense card), expect to rotate blades more often. The included quantity makes that realistic.

The cutting mat and ruler

The A4 self-healing mat (roughly 11 x 8 inches) is the right size for a desk or kitchen table setup. The grid printing is accurate enough for layout and quick measuring, and the mat heals well from typical scoring and slicing—after a day of normal use, the surface looked clean with only faint witness lines. For large posters, foam board, or fabric, the mat will feel tight. If your projects frequently exceed letter-sized media, consider pairing the kit with a larger mat and keep this one for portable work.

The 12-inch metal rule is handy and lies flat. It’s straight and stiff enough for guiding cuts without bowing. For the most secure straight cuts, I placed my off-hand fingertips down the rule’s length to prevent sliding and kept the blade angled slightly away from the rule to avoid biting the edge. If you do a lot of long, fast cuts, adding a strip of painter’s tape or a magnetic straightedge upgrade will improve traction and protect the rule’s finish.

Storage and organization

The compact case keeps the handle, blades, and accessories tidy and easy to grab. It’s sturdy enough to toss into a backpack without worrying about a blade escaping. I appreciated that the blades aren’t rattling loose in a baggie; the case layout makes it quick to spot the shape you want. That said, once you start mixing used and unused blades, organization requires discipline. I keep a small scrap of cork inside the case to stick “in-progress” blades so I know what’s still sharp versus spent.

Accuracy and control

The kit rewards light, progressive cutting. One of the biggest improvements most people can make with a craft knife is pass discipline: three effortless passes beat one forceful cut every time. With the handle’s grip and the ruler on grid, I could slice long, accurate strips of card stock without the “banana” effect that happens when a handle rolls or a rule wanders. Circles and small arcs are competent with a curved blade, though you won’t match a dedicated circle cutter for perfect repeats.

Safety and maintenance

• Always retract or cap the blade between tasks. The kit’s case helps, but muscle memory matters more.
• Use the mat. Cutting on wood or glass dulls blades faster and is harder on your wrist.
• Change blades before they force you to add pressure. Extra pressure invites slips.
• Dispose of used blades in a puncture-proof container (an old metal tin or a dedicated blade bank).
• Wipe the handle and rule after cutting sticky media; adhesive buildup is what leads to jerky cuts.

Where it shines (and where it doesn’t)

Strengths:
- Comfortable handle for extended sessions and straight-line control.
- Practical blade mix for most hobby materials.
- Handy, accurate A4 mat for small projects and portable work.
- Metal rule that’s straight and long enough for letter-sized stock.
- Compact, organized case that keeps everything together.

Trade-offs:
- The mat size limits larger layouts; many users will eventually want a bigger cutting surface.
- Blades dull quickly in soft woods and dense chipboard; keep spares handy.
- The handle’s thicker profile favors control over ultra-fine, delicate freehand work.

Who it’s for

If you’re starting out in paper crafts, model-making, cosplay detail work, or general shop prototyping, this kit covers the essentials without demanding add-ons. It’s also a smart secondary setup for experienced makers who want a compact, portable kit for travel or a secondary bench. If your work leans heavily toward large-format cutting, thick foam, or repetitive wood shaping, consider supplementing with a larger mat, a non-slip straightedge, and specialty blades or saws.

Tips for better results

• Use the grid to square your stock before trimming; it reduces compound errors.
• For foam board, score the facing paper first, then deepen the cut—don’t try to slice through in one pass.
• Angle the blade slightly away from the rule to preserve both the rule’s edge and your blade.
• Rotate blades proactively. I mark a tiny dot on the spine each time a blade starts to drag; by the second dot, I swap it.

Recommendation

I recommend the Black & Decker craft knife kit for anyone who needs a reliable, all-in-one setup for paper, card stock, thin plastics, vinyl, and occasional soft wood detail work. The comfortable handle, useful blade assortment, accurate A4 mat, and metal rule make it a practical package that encourages good cutting habits. Its compact case means it actually gets used—on a desk, kitchen table, or packed for a workshop—rather than becoming a drawer orphan. The main limitation is the mat size; if you routinely tackle larger projects, plan to add a bigger mat. Otherwise, this kit strikes a sensible balance of comfort, control, and convenience at a desk-friendly scale.
