That's actually rather bad ass. Never seen it before.
I don't carry any tools on hill. Like others said you can usually find a bench with a screw driver. Then the lodges usually have stuff you can use. I have also asked lifties before when I needed a phillips and they have in the hut every time ive asked. I assume most of them would have a Phillips if you asked.
For an iron I just use a cheap $10 one I got a wal-mart. I am getting a Dakine one this year tho for my "shop" I have set up in a spare room. Dakine has a nice tune up kit you can get that comes with everything you really need and a nice carry along T shape driver.
