One on top of the other

Both outlines on one axis, at the same scale. Sizes come from the makers’ published girths; where a usable cut-out exists, the profile itself is traced from it. Where they overlap they’re the same; the gap is the difference.

Side by side at the same scale

Drawn to scale: sizes from published girths, and the profile traced from the cut-out where we have one. Point positions along the shaft are approximate.

How the numbers compare

Differences of about ¼ inch or more are highlighted. Blanks mean the maker doesn’t publish that point.

	S2 Thumbdrive	S3 Thumbdrive
Total length	6.5″	6.8″
Widest girth	5.1″	5.2″
Narrowest girth	3.3″	3.5″
Firmness options	soft	soft
Knot	no	no

Which one should you get?

Every line generated from the spec deltas above.

Stepping up from the S2 to the S3 adds 0.1″ of girth: 5.1″ around becomes 5.2″.
That’s a modest step: comfortably inside the half-inch-per-step increment people usually recommend.
Both sizes come in the same firmness options (soft), so feel isn’t a variable here — only size is.
