Bump for good design and production.
Glad to see the 'Hawks realized. Sweet, you guys.

Nice, Bryan.
Is the head hole for help with cleaning it if hammered? Room for a small quicklink to funkness cable?
If more buried, like RURPs on the Triple Cracks, it might be nice to have a "dog leash clip" style wire hook, good for a few hundred pounds, which could fit into the RURP hole and assist in cleaning fixed RURPs or Tomahawks.
But something with a smaller profile, no swivel and more strength would be best.

Cam Hooks hanging to dry after a dip in corrosion inhibiter:
Is that done in a hot salt bath, to produce the black oxide?

I got my Moses Cam Hooks from Mountain Gear and went straight out to my local crumbly beach cliff to try them out.
The come in three sizes:
Mini - $7.95
Narrow - $8.95
Wide - $9.95
Shipping from mountain gear was $4.95 and they took 2 business day to arrive.
I bought the Narrow and Wide. I found that the Mini Leeper Cam Hook just never was that useful. There were only a handful of times i remember using it on El Cap. I would say only get Mini Moses if you are doing some cutting edge clean aid and want every possible tool. Otherwise I find that the narrow size works 90% of the time. The other 10% of the time i use the wide. So if you can only buy one, get the narrow.
After the Moses Cam Hooks arrived, i pulled out my old Leeper Cam Hooks for a size by side comparison. But i couldn't find my wide Leepers...Doh! ( If anyone is borrowing them from me, please return to me.)
Ok, so for this comparison we will only be looking at the Narrow size... which is cool because that is the most useful size anyway.
As you can see, in the photos below they are pretty much identical. Only by very care comparison can you tell that the bend is only slightly different, the eye on the moses is a little smaller, and moses is a little shorter... but they are essentially identical.
HOW DID THEY COMPARE?
In full disclosure, i was testing in crappy coastal rock. A real test is necessary in granite, where these will generally be used. I will do that next week on El Cap. So for now, this is just a "first look" report.
In bigger cracks, the Moses cam hooks worked just as well as the Leepers. Sweet!
I then put them both in some pretty crappy shallow placements:
Here i discovered that the Leepers did hold a little better. What? How could this be? They are almost identical, right?
I was pretty surprised at first. Even a little worried. But then i noticed a key difference:
As you can see in the photo, the edges of my Leeper Cam hook are worn down. (I am pretty sure they started out just as square as the Moses edges). Just that little difference made the Leeper more secure in a few super tenuous spots.
So is it time to file down my Moses cam hook a little to make it more like the Leeper? Not yet. Like I said, this was crappy ocean rock. not an ideal test environment. Ill go to Yosemite next week and let you guys know how they turn out... in the mean time, i will still be looking for my missing wide leeper!!

Hey, thanks all!
Nice field-testing on the cam hooks, Chris! The bent versions of the Tomahawk are designed for use in corners – the top bend allows for greater hammer contact and reduces glancing blows when placing the piece and the bottom bend provides clearance for the cable, so that it doesn’t get pinched between the stem and the rock and start to fray. The bottom bend is not intended to add camming action. I have tried to stay away from any significant camming action with a beak-type piton of this size and am not sure, but think that the “blade” of a Tomahawk, Beak, Pecker, etc. is the wrong shape, too thin, and not strong enough to be seriously torqued on – compare the metal thickness between beaks and cam hooks. Any engineer types out there have any comments on this? As far as clean placements go, the Tomahawk was designed to be used as a hook in beak scars or constrictions in thin cracks, and has better hooking action than a #1 Pecker or Beak.
“Is the head hole for help with cleaning it if hammered? Room for a small quicklink to funkness cable?”
Clint, the “hole in the head” is mostly for tying-off the Tomahawk if it is placed in a horizontal crack. The hole can also be used to “funk” the Tomahawk out but I hadn’t thought of using a quick-link – just webbing. Great idea! Although it is possible to use a funkness device for cleaning, the Tomahawk was designed with several hammering surfaces, which make it much easier to clean and reduces the chance of it becoming fixed. A funkness device should be used gently and as a last resort, to preserve the placement for future use. A “pull tab” made of 1/2" tie-off webbing can be threaded through the hole to assist in the removal of hammerless placements.
3/16” quick-link, $1.97 at Home Depot.
Back to your regularly scheduled cam hook program…

looks like someone else also has a clone of the Cam Hooks
http://www.brasovia.com/products/product-BR600-0005.html
I've never used cam hooks, still learning the aid game, but I actually ordered a set of these...
Still don't have them yet, but I did get this, I wonder what a better version means...
"but we will have a much better version available in 3 weeks or so"
So I waited and got these new ones for a steal, the company is in Canada so a whole set of these is like 20 bucks...
I will try and get them out with a big wall veteran (who will hopefully teach me how to use them like a pro). I think some sizes are shipping on Friday..

Thanks for continuing such awesome designs, Moses... I have a number of Moses hooks.
My Leeper and Moses hooks seem identical all except for the mini camhook. Am I the only one who's noticed this? The Moses Mini is a bit wider, longer, and significantly thicker. I had to grind mine down. With how thick they are, it doesn't appear that you can get them into much smaller placements than the medium sized one. It would be nice if you could make them the size of the old Leeper.
