The two sided bits give my multitool twice the capability. They fit in the Leatherman bit driver and the Gerber Armbar very well. You can find rubber bit holders on eBay to carry them in your sheath.
These are high quality bits. I bought these to use in a Leatherman bit driver, but they are too long to lock in properly. The bits lock into my 1/4" hex Chineseum screwdriver handle and work great.
