In reply to Jimp97:
I've made a couple and have a few MSR ones. The end that you hit when you're using them in top-clip mode gets pretty bashed after a while so I rivetted two small pieces of U-shaped steel over one end to protect the alloy.
A cable attached in the centre is really handy for vertical mid-clip placements but it does add a fair bit of weight and can be a nuisance when you're carrying the stake. If you do fit a cable, I'd make the loop where it attaches to the stake slightly larger than the diameter of your ice axe shaft so you can push the axe through there for the Saxon cross placement.
The position of the holes on the MSR ones works well so I'd copy those closely. For example if you carry the stake on your harness you can clip the second hole down from the end and the stake hangs at a handy angle away from your legs.
Apologies in advance if you already know this but the key to strong snow stake placements is matching the placement type to the snow conditions so getting familiar with the different techniques and using the right one at the right time is the important part. As cb294 says, the snow is generally the weakest link.
