Horizontal Infinity adjustment tool for M3: what makes the most effective tool?

[leicamshooter]

The horizontal infinity needs to be slightly adjusted on my M3. I

measured it against a very bright star/planet and found this to be

the case. The angle of attack makes it difficult to use a straight

flathead driver. Short of purchasing a special Leica tool ($) for

the job, what various options do I have, and which one is more

effective? Thank you in advance for your responses.

I used this to adjust my M4. You may wanna dull it a little.<div></div>

The end of a cheap, stainless-steel film clip works well. I keep one in my bag.

I use the rounded end of a 6" steel pocket rule (General brand, usually) from the hardware store. The thickness is of the rule perfect for the slot in the screw, and the rounded end lets you not need to be in perfect alignment with the screw. And it fits in your bag without taking up any space to speak of.

Thank you for the responses. I had a hard time finding these

simple tool options here in Alaska. So what I did was get a

"Allied Pro" 1/8 x 3" slotted screwdriver. The handle is rubber so

it's very easy to hold. Gently I used it to turn the screw counter

clockwise. I reassured the roller by placing a finger against it so

not too much uneven pressure was being placed upon it. It was

a slight nudge and gently done. I tested it against the very bright

moon and planet last night and it worked! Took a few seconds

at the most. The most difficult thing was finding the right tool.
