The limpet turned out to be very popular and other services took it up (it appears in Cockleshell Heroes by the way). It was a magnetic, hand attached bomb.

David Howarth on the shore staff at Shetland describes people scheduled for insertion having all sorts of gear. Some are interesting and a bit Cliffhangersy like knuckledusters. I get the impression that a lot of it they just took along: they had more leeway than the regular service which had to standardize.

A hand to hand weapon is more a desperation tool. Some things, like sentry removal would make it relevant.

A lot of the exotic hand to hand equipment though, seems to figure more in the "why not" category than in something seriously relied on. If it isn't cumbersome it might as well be put in especially if it can be used for something else.

The Sten was favored, more because it was low budget than anything else if the wikipedia article is correct

The Welrod was liked because it was small and also could be taken apart. It also had no manufacturer markings though it is not clear why that mattered. Apparently it could be disguised as something else.

Basically I would guess that most of their best weapons will be centered around making bangs. Stealth is the best tool for mere survival.
