I don't carry anything in my pants pockets because I like to turn the front pockets out and tell everyone I will do my impression of an elephant. LOL But seriously, I carry 5 nickles and 4 pennies for coins thru table and sympathetic coins. I have a coin purse with four half dollars and shell for coins across. A few packet tricks(Doubleback, Capitulating Cards, Marked Cards, and Ultimate Backflips) and a regular deck with one r/b db card.

Very cool...thank you! (BusinessCOIN Prediction is my effect.)

Sponge balls, a few rubber bands, coins, and a few items in my wallet for a mind control routine.

Probably been mentioned. But if you have the Invisible Deck you are set to go. Also if you have the room a Stebbins stack deck with the Invisible Deck can be unbelievable.

5 and 1 (Ammar's version)
ITR
TT (cigarette vanish)
Mogars' Color Changing Knives
Crazy Man's Handcuffs

Ive been carrying a stripper deck, a sharpie, a few pennies for a coin trick I do.

A deck of cards, it's easy to remember and gives me a wide selection of effects.

I usually forget to bring anything else.

TT, deck of cards,PK Ring,expanded shell coin & Twisted Sisters.

New addition to my repertoire: Hundy 500. Hands down it's THE most requested close-up effect.

I always carry two #16 rubber bands to do my RB act, B'Wave, The Wonderland Bill, A TT with a Mis-Made Bill in it, and just a plain deck of cards.

ALWAYS Carry?
Money, rubber bands, sanada, business card, 3 card monte, 2 gimmicks it all fits in my wallet. I also have a couple of gimmicked credit cards for fun.
Routines I perform are
1. $50 production
2. Crazy Mans Handcuffs
3. 3 card monte - in their hands version
4. Matchbox mambo - if I can find matchboxes in the restaurant
5. Standing Card (Gaeten bloom effect)
This gives me 10 minutes of "show us a trick" if I get asked.
Used to carry the pothole trick also.

I never leave home without:
1. D'Lites
2. Color Monte
3. Color changing knives
4. Kennedy Half dollar
5. Extreme Burn

To be honest, the only things I "always" carry, are a pack of cards and a few good-sized coins.

1) D-Lites
2) deck of cards w/ gimmick for rising card
3)Floating match always floors them
4)Bite out quarter
5) and always a post it pad & pen for step ahead professor

1. Coins Across by David Roth (uses 4 halves and an expanded shell
2. Penny and Dime transposition (Check out "On the Spot" by Greogry Wilson.)
There are so many things you can do with coins and bills!
3. Deck of Cards (two if one is gimmicked)
4. TT with Red Silk
5. Loops or IT Reel

1. 5 to 1 Bill Transpo
2. Hot Rod
3. Silk and Coins-- any number of impromptu effects
4. Pencil for pencil through dollar bill
5. Scotch & Soda

I'm ALWAYS wearing rubber bands for "Crazy Man's Handcuffs".
I try to carry spongeballs/sponge bunnies with me.
I've recently been wearing STS and...
I carry a Hot Rod or Scotch & Soda, sometimes.

So...I guess those would be my top five, even if STS doesn't come out of my pocket. Also..."abercrombe" that is a disgusting/funny "elephant impression" comment.

In my pocket- A pack of cards and my wallet.

In the wallet- 2 rubber bands, 4 halves and 1 English penny, a small envelope w/ a prediction, and (soon) Extreme Burn.

1. B'Wave (my "quick trick")
2. Entourage (for when I have more time)
3. Deck of Cards (I do Dr. Daley's Last Trick most often, though.)
4. Skinner's 3 Card Monte

I'll be getting NFW soon and maybe a longer trick by John Bannon, so let's see if those make it into the "always on me" category.

I don't have NFW, but if it plays like the demos I've seen, it should be "always on you."
