Wahl Balding Blade: Which One Fits and How to Set It Safely

Wahl's detachable clipper blades run on a numbered scale where higher numbers cut shorter - a #10 leaves roughly 1.5 mm and a #40 is surgical-close (the full breakdown is on the blade size chart). The balding blade sits outside that numbering entirely: it is sold and listed as "6X0 ultra-close," a separate closeness rating built for one purpose - taking hair down to the skin for a bald or near-bald finish, closer than any guarded detachable blade is meant to go.

Model 2105 is the current replacement part for the dedicated Wahl Balding clipper. It is listed in the full model-to-blade matrix on the clipper models page alongside the rest of the range.

The distinction that matters: a standard taper clipper set to its shortest lever position still is not built to run bare against skin the way the 2105 is. Trying to get a balding-close finish out of a general taper blade is how people end up with an uneven, irritated result instead of a clean shave.

No. It is made for the dedicated Balding clipper and is not a drop-in replacement for a Magic Clip, Legend or Senior - those run their own blade families (stagger-tooth, wedge and the Senior's own top blade respectively), covered on the replacement blades page. Most Wahl clippers in this line are built around one fixed, very close cutting length rather than a taper lever, which is exactly why the machine exists as a separate model instead of being a setting on a regular clipper.

Before ordering, check the number stamped on the blade you are removing rather than assuming by the clipper's name - the same rule that applies across the whole range.

Replacing a bolted 2105 follows the same pattern as any full-size Wahl taper blade, with less margin for error given how close it cuts:

• Turn the clipper off and brush out any hair packed around the old blade before removing it.
• Undo the mounting screws and lift the old blade away, noting how the cutter sat against the still blade.
• Seat the new 2105 and start the screws loosely on both sides before tightening either fully.
• Square the cutter so it sits just barely recessed behind the still blade's tips, then tighten evenly, alternating screws rather than driving one home first.
• Oil the teeth and test on a low-risk patch - arm hair, not a hairline - before using it properly.

Because there is no guard to soften a bad setup, getting the alignment right matters more here than on almost any other Wahl blade. The full technique is on the Wahl blade alignment guide if the cut comes out uneven after fitting.

A few habits make the difference between a clean shave and an irritated scalp: go slow on the first pass rather than pressing for speed, cut with the direction of hair growth before trying against it, and keep the blade oiled - heat plus direct skin contact is what turns a fine blade into an uncomfortable one. Rinse and dry the blade after use rather than leaving it damp, since rust on a blade this close to skin is both a performance and a hygiene problem.

Replace the blade when it no longer glides completely flush, when a fingernail run along the edge catches on a nick, or when it starts leaving faint stray hairs it used to take cleanly - all signs the ultra-fine edge has dulled past what oiling and cleaning can fix.
