DaRn! I "forgot" one:
Large 4" and larger closed Sunfish/elephant toe ("elephant
toenail" is the small around 3.24-3.5" closed version)/ "British Rope Knife" (tho no historical evidence they used the pattern)/Whaler/"Pocket Axe"/"Emergency Spatlua" ... and about another 80 names it is known as.
Large spear point and large pen blades.
Advantages:
Due to the shape, it does not "print" carried loose in the pocket of even the lightest business trousers, despite being a large knife.
Shown with a (US) Old Timer 8OT for size comparison.
The equal end is a hair over 4.25 inches closed. The two sleeveboards are 4 inches closed.
All three are Rough Rider.
Rough Rider and I believe (offshore) Marbles, currently have the Sunfish in production.
Sorry. I cannot afford the GEC and vintage Case knives in this pattern. (I have spent less for licenseable & driveable cars and ridable motorcycles. than those knives sell for.


)
I used the equal end to whittle/carve a lock mortise in some seasoned oak. It handled the job just fine. It didn't
need it, but I did strop it after I finished., and have 440a blades
