1664. This looks like a grappling hook of some kind. A collapsable one. But
most grappling hooks have more curved hooks on them. Sooo....??
1665. This looks like somthing welded onto a horseshoe. But it could not be
used as a horeshoe.
1666. This looks like a seatbelt cutter. Used at accident scenes when you
can not reach the seatbelt buckle and you need to free the victim.
1666. I was going to say gut hook but I think you're right. Orange
1667. Boot scraper. Hammer it into a log and scrape away. Sort of like

Perhaps an oarlock then ?

1664 Tree canopy penetrator rescue tool. Drop it with a winch
through the trees with
a helicopter. Fold out arms, sit on arms and strap on.
deployed in Viet Nam???
1665 No idea. Gauge for horseshoes? Primitive ice scraper?
for "horseshoe shuffleboard"?
1666 Strap/parachute shroud cutter. For getting yourself free of
that pesky chute
when you are hanging from a tree.
That large yellow hook looks like a jungle penetrator for a winch on a
helicopter. It was weighted and used in heavy cover to get the hook to
downed air crews or whoever needed pickup by helo.
The pocket knife is a shroud cutter on a survival knife the Navy at least
gave to air crews. I have two in my tool box. The shroud cutter blade that
is shown was also a switchblade. There is also a 3 or 4 inch conventional
blade on it.
Talk about reminders of the good old days.
Number 1666 is an airmans knife. The hook is designed to cut shroud lines on
parachutes. Especially usefull when hanging in a tree.
The originals were a switchblade type knife with a slider lock and a
pushbutton for use with one hand.
They were in every Vietnam era airmans survival vest.
1663: A cigar lighter and a castinet
1664: Very, very, large toggle bolt
1665: Novelty plant hanger
1666: Very poorly designed buttonhook
1667: Looks like part of a gate latch
1668: Used by the most fastidious of cabinetmakers to make sure their drawer

1663) Hmm ... a bunch of "almost"s.
The one on the left is sort of like a sensor for positioning the
cutter on a milling machine -- it depends on electrical contact
between the ends made by the milling machine body, and a LED or
a lamp would be lit in the windows, powered by a cell which is
under the hex plastic screw head.
But -- there is no LED or lamp visible, and the battery
compartment would need to be on one side and there would need to
be a conductive surface insulated from the rest, and I see no
signs of that.
Or -- it could be a holder for optical testing of the contents
of a glass container placed in the body so light could go
through the windows and the contents. The plastic hex headed
screw would be removed to allow installing the container.
Something like measuring transmission through a range of light
wavelengths in a spectrophotometer.
As for the item on the right -- it is *almost* like a sine
plate, except that it needs to hinge on a cylindrical roller,
and to have another roller at the other end to be held up by a
stack of gauge blocks to allow setting a precise angle by making
the stack of blocks total measurement match the sine of the
desired angle. But -- it doesn't have those features, so it is
some sort of hinge -- except for the angled surfaces on one
side, which suggests that its function is to guide something into
the proper and precise position as it is closed and the knuckles
1664) A folding anchor partially out of its storage bag and partially
unfolded (two of the four flukes).
Perhaps some sort of dry-land grapnel instead of an anchor?
1665) Made from a horseshoe.
Perhaps to mount on a wall to hang horse accessories?
Perhaps to actually fasten to a horse's hoof to discourage
putting weight on that leg to speed healing?
1666) At a guess, a paratrooper's knife for cutting the shrouds
(ropes) of a parachute once you touch down to keep the 'chute
from dragging you along the ground.
1667) Drive it in the ground beside the door and use it to scrape
mud off your shoes?
1668) Hmm ... interesting device.
It looks as though the mounted glass plate is designed to have
film pass under it, and then the micrometer head (calibrated in
mm, not thousands of an inch) moves the plate, frame and film,
presumably under examination with a microscope. We've got a
photo of the reverse side of a glass scale calibrated in mm and
(I believe) two tenths steps.
I would like to see it out of the box from several views,
because I suspect that it is intended to mount to some other
I would also like to see closeups of the various accessories
which might be more informative.
At a guess, it is used for measuring the position of emission
and absorbtion lines from photographing the output from a prism
or a diffraction grating.

1665 Farriers new shoe "setter"--Heated in the forge & pressed into the
newly dressed hoof , it burns in a solid tight fitting seat.
1666 field dressing gut knife---cuts abdominal flesh w/o opening
1664 - Retriever bob. Used to retrieve items (men material whatever).
Dropped from a helicopter and designed to penetrate the canopy of the
trees. Then lifted back out once the items are secured.
1665 - Looks like a hot shoe, could also be a wood burning tool.
1666 - Get hung in your chute and it will come in handy!
1667 - I can look at those on the neighbors house. They are used for the
metal downspouts. Wire wraps the ears and the spike gets driven into the
wood. They are also worth a few bucks to the folks who restore old homes.
1668 - Cartographers measure?
1666. Back in the old skydiving days (mid to late 70's) this particular
knife was carried by some for cutting the extremely rare line that
resulted in (mostly reserve) 'line over' malfunctions. maybe 20% of
jumpers at the time even bothered carrying them.
Some reserve parachutes back then also featured (marked) lines you could
cut (after deployment) giving them a little forward drive and limited
steering ability. (Other reserves featured quick release devices so
cutting lines wasn't necessary... and still others were steered by
pulling the marked lines. You needed to know your equipment.)
As the 1666 knife came from the factory, they were crude, not all that
sharp, and required a lot precious time and dexterity under pressure to
find, open and use... easy to drop too, particularly with gloves. But
they were the best available...
Later, razor 'Hook Knives' featuring two finger loops became available.
They stow in a simple quick release Velcro pouch attached to your
harness main lift web. Just stick two fingers through the loops, pull to
extract, and your ready to cut anything.
See the 'Happy Hooker' and 'Z' knife in the page below for the new ones:
Most jumpers, (both then and today), will never have use for a hook
knife, and probably won't personally know of anyone who's needed one
