Here ya go... Truly is the "best screw in the hunting industry"...

I've got about 200 of these puppies, ranging from the EZY climb deluxe to the folding tree step (most compact) to the detachable steps (thank God I was using these the day I had my only stand stolen so far).
Seriously, I just laugh at people who write about having to carry "step starters" into the woods, either made by a step manufacturer who's step is junk (cough * cough* Ameristep * cough

. At least the old ones... I have been shown a pic of their newer ones which look more like copies of the Cranfords.) or electric drills or whatever. Cranfords offer TRUE one-handed easy starting, and I can seriously get up almost as high as I can with my four lone wolfs in maybe an extra minute more than it would take me with those. I use my climbing sticks in conjunction with my Alpha Hang-On a lot, but when I want TOTAL quiet and the lightest, most-packable, quietest setup I can get in... I take my Cranfords in with me.
They're only sold in pro shops as far as I know, and they're probably a bit more expensive than the "average" step... but -- trust me -- this is no average step.
