Clipped from Wikipedia: Daredevil's signature weapon is his specially-designed billy club, which he created. Disguised as a blind man's cane in civilian garb, it is a multi-purpose weapon and tool that contains thirty feet of aircraft control cable connected to a case-hardened steel grapnel. Internal mechanisms allow the cable to be neatly wound and unwound, while a powerful spring launches the grapnel. The handle can be straightened for use when throwing. The club can also be split into two parts, one of which is a fighting baton, the other of which ends in a curved hook.
Clipped from marvel.wikia.com: In early canon, the Billy Club had a retractable microphone, a miniature tape recorder, and a chamber for firing projectiles.
Fun Fact: Daredevil's Billy Club has been lost or destroyed on more than one occasion:
- Daredevil #80 lost in New York Harbor and never found.
- Daredevil #116 destroyed battling Death Stalker
- Daredevil #122 broken battling Nightwing.
First appearance: Showcase #4 (October, 1956)
History: Flash's Costume Ring is a small ring with a spring-loaded opening. Barry Allen, the second Flash, used this ring to compress and conceal his costume while operating in his civilian identity. By thumbing a small stud on the side, the top of the ring opened, releasing the costume (chemically treated to shrink), allowing Barry the ability to change clothes at super-speed.
How it Works: The Flash's alter ego, Barry Allen,
is a research chemist who is accustomed to fabricating his own test
equipment. The suit-concealment ring and repeatably-compressible suit
was a great challenge. The ring is a combination of miniature machining
and traditional lost-wax jewelry casting and is made of a high grade
stainless steel. For the Flash's costume, Allen developed a thermally
stable costume, suitable for high speed travel. The suit is made of
highly compressible synthetic silk with ultrasonic welded components.
The key to the suit's effectiveness is bonded outer layer of
ultra-smooth Teflon which aids in thermal dissipation and eases the high
speed passage through atmosphere or other media. The suit fits into the
ring through a series of carefully calculated foldings. The suit is
compressed so rapidly that great heat is developed as it is placed
inside the ring. As the suit cools, a partial vacuum is formed which
holds the ring halves closed. The suit forms its own seal against the
only opening, which is the release stud. When the ring is opened, the
synthetic silk molecules uncoil and absorb atmospheric gases, expanding
to full size very rapidly
Wally West, the third Flash, also uses one of these rings. Barry's grandson, Bart Allen, used a similar ring to hide his costume while he was the Flash, and another to house his Impulse and Kid Flash costumes (he does not remove this ring under any circumstances, at least not willingly). Bart's first costume ring, that in which he stored his Impulse costume, was a gift from Wally West, and a replica of Barry's original.
Other Non-Flash Rings: Barry
Allen gave Flash Costume Rings to other members of the Justice League,
containing their own costumes, as seen when Green Arrow has Arsenal steal the one Green Arrow had gotten from Barry, which had been in the Flash Muesum's collection "Friends of the Flash". His costume is stored inside of it and it says "To Ollie, Run fast. - Barry". Ollie makes it into his engagement ring for Dinah. The other members of the Justice League didn't use them because they weren't fast enough to get into their costumes.
Fun Fact: Green Arrow used the ring given to him by Barry Allen as a gift when he proposed to his longtime girlfriend Black Canary.
Fun Fact: The Flash has shown the ability to vibrate and compress his molecules to actually hide himself inside of the ring when the situation calls for it.
This post is dedicated to the thing that holds up a hero's pants. For Batman it is his Utility Belt with it's numerous gadgets. Batman's Utility Belt has always had special place in my Dork heart.
Fun Fact (clipped from Wikipedia): Batman historian Les Daniels credits Gardner Fox, (the first writer other than Bill Finger to write the adventures of Batman in Detective Comics), with introducing the utility belt concept in Detective Comics #29 (July 1939). In its first appearance, Batman's utility belt "contained choking gas capsules." Two issues after the utility belt debuted, Fox also wrote the first appearance of a bat-themed weapon, when the batarang debuted in the story "Batman vs. the Vampire" in Detective Comics #31 (Sep 1939).

OTHER UTILITY BELTS
Robin's Utility Belt (from the comic book). This belt never made any sense. Why keep all the pouches on the inside. Stupid Robin belt! No wonder you never got a toy made .
Joker's Infamous Utility Belt (from the comic book). Now this was a cool idea a little evil tit for tat accessories. 
Other Super Heroes Utility Belt Toy made by Remco released in 1978. Of course none of these made any friggin' sense. Wasn't the Hulk's belt just a tied rope and what does a man who can move planets need with gadgets. BUT whatever, I would have still loved to have had these as a kid.
Fun Fact (clipped from Wikipedia): Gadgets in the Belt from time to time.
Batarangs: A customized throwing weapon used by Batman. Interpretations of the weapon have varied from the boomerang to the shuriken. Recent interpretations have shown a large array of different types and sizes for different effects (i.e. blunt impact, edged, slashing).
Bat-cuffs:Bat shaped handcuffs, resembling the kind used by Special Forces units. These restraints are made of a lightweight diamond-impregnated nylon overlaying a banded steel core. Using a one-piece design, they slide closed and have to be cut off. Batman has given a special tool with a diamond-edged cutting implement to the Gotham PD for removal.
Bat-monitor with Tracer: Used to track enemies Batman can't follow closely.Bat-Micro camera: A miniature camera
Bat-Communications device:Often an earbug, but sometimes handheld.
Bat First aid kit.Bat-Grappling hook and Grapnel Gun: Used to fire a bat-shaped hook attached to a high-tensile wire line in order to scale sheer surfaces and/or swing across gaps. Grapnel Gun is similar to a grappling hook, the line gun uses a strong clamp attached to a high-tensile wire for scaling surfaces and/or traversing gaps. It can be recovered by releasing the clamp and rewinding the cable. It was based from one that is designed as compact climbing gear for commando units.
Bat-Night vision goggles: Using Starlite infrared lenses to see thermal output in low light or non-lit situations. Currently built-in to Batman's cowl.
Bat-Flashlight: A simple flashlight. Batman uses it in numerous episodes of the animated series, usually when looking for clues, or through private files in the dark.Bat-Kryptonite ring: Stored in a lead box, it is reserved for emergency use against a rogue Superman and/or other Kryptonians.Bat-Lock pick: Sometimes kept in the gloves instead.
Bat-Master Key: Sometimes mistakenly called a skeleton key is perhaps the simplest tool in Batman's utility belt.
Bat-Miniaturized toolkit.
Bat-Rebreather: Allows Batman to breathe underwater or in a vacuum. Depending on the writer and/or artist, it may also be incorporated with the gas mask.Bat-Marble: Rolled down stairs to imitate footsteps. Depicted as a magnetic metal ball in the "Hush" storyline arc.Bat-bolas:Thrown around the feet of Batman's enemies to tie them with a composite-nylon cord. Often causes an escaping opponent to trip. With the push of a button in Batman's glove it can deliver an electric shock.
Bat-Cryo Capsules: Small capsules that release a cryogenic acid upon the breaking of the shell.Bat-Darts:Tipped with tranquillizers.
Bat-Miniature smoke grenades.
Bat-Smoke pellets: Often used to quickly provide cover for Batman's stealthly exits and entries. Knock-out gas pellets are used as well for non-lethally incapacitating opponents. Lachrymatory and regurgitant agents are deployed by throwing or breaking open the small hardened-gelatin spheroid capsules.
Bat-Stungun/taser: used by Batman to stun his enemies with an electrical shock to temporarily paralize them.Bat-Goo gun:A hand held foam projector that fires an adhesive-like substance to incapacitate opponents.
Bat-Stun (Flash-Bang) grenades: Emits bright light and loud sound to blind and stun enemies.
Bat-Thermite grenades: An incendiary used to burn through obstacles. In Batman: Year One, the thermite charge ignited accidentally and destroyed the utility belt. Although they are identified as Thermite, it is safe to assume that Thermate is used instead. (The former is a World War II technology which has largely been replaced by the latter.) In Judgement on Gotham (1991), Batman is equipped with a phosphor-based incendiary device.
Bat-Collapsible sword: seen in Batman: The Brave and the Bold, sharp enough to cut through steel objects such as Clock King's robots. Resembles a Lightsaber.
Bat-Saw: used in Batman & Robin to cut through Poison Ivy's vines, slightly resembles Gabriel Van Helsing's tojo blades.Bat-Flamethower: a miniature flamethower that was used on BatBane in the "Ghosts of Batman arc".Bat-Acetylene torch:A strong miniaturized laser used as a cutting tool.Bat-Heater: mini bat shaped tool used to melt ice.Bat-Cache of cash.
Bat-Evidence bags: Bags in which to hold evidence.
