This is a total quirk of mine, but I simply cannot regard the Newton as a double-knock—it’s the damn conical tip section!
The entire purpose of a double-knock mechanism is to protect a vulnerable lead sleeve from breaking in accidents…
But conical tip sections are indestructible!
Seems ridiculous to me, and the experience of knocking to reveal a lead sleeve is drastically different from a knock that reveals a conical tip.
(I realize this is so far into the weeds, but y’all might as well know how I feel about it 
)
