Here is a Guide I found on leather uses of different thicknesses, It is a great guide to help choosing what weight to use. First post shows conversions of different units of measurements

Recommended Uses for Leather Weights:
0.6-0.8 mm: Generally used for linings and small personal leather goods.
0.8-1.2 mm: Used for wallets and lining belts, as well as women's shoes and garments.
1.2-1.6 mm: Craft weight leather, good for men's shoes and lightweight chaps.
1.6-2.0 mm: Intermediate weight, used for handbags, belts, and ideal for chaps.
2.0-2.4 mm: Ideal for work boots, handbags, and handbag straps.
2.4-2.8 mm: Popular weight for hand tooled handbags, contour belts, shoulder straps, knife sheaths, and small tool pouches.
2.8-3.2mm: Good weight for narrow belts, handbags, saddlebags, pistol holsters, knife sheathes and collars.
3.2-3.6 mm: Good for medium width belts, rifle scabbards, holsters, and motorcycle bags.
3.6-4.0 mm: For wide belts, halters, head stalls, bridles, breast collars and reins, tie straps and show harnesses.
4.0-4.4 mm: Used for saddles, halters, bridles, breast collars, reins, linesmen's belts, tie straps, dog collars and carriage harnesses.

these would the most useful sizes that a bushcrafter would use but as you can see in first post it does get a lot thicker

Your a mind reader Auscraft...was just thinking the other day..how do I choose the leather for a project, I know I can go to a leather store and just pick up what I need by look and feel but buying on-line is a different situation.

thanks for this

little on tans commonly found in OZ and a few of thier uses. Chrome leather is alot cheaper than Veg depending on thier use you do have choices.
Chrome Tanned Leather
Chrome-tanned leather is tanned using mainly chromium salts. It is softer and more supple than vegetable-tanned leather and does not discolor or lose shape as drastically in water as vegetable-tanned leather. Chromium-tanned hides tend to be more receptive to color and retain more of their elasticity.
Uses : bags & Handbags, Personal Leather goods.

Vegetable Tanned Leather
Vegetable-tanned leather is tanned using tannin and other natural ingredients found in trees and plants. The result is leather that has greater body and firmness than chromium-tanned leather with little or no elasticity. Vegetable tanned leather tends to have much higher tensile strength than chrome-tanned leather.
Uses: Perfect leather for tooling, embossing, molding, dyeing & oiling. Uniformly absorbs dyes and oils. Dries to a firm, long-lasting shape.

Knife Sheaths
Almost exclusively made with vegetable tanned leather with the exception being the lined area's that do not come in contact with metals. The chromium salts used in chrome-tanning can corrode some metals over time.

The descriptions and basic use info came from Web some time ago and did keep record from where and haven't found again. There is a fair bit more info on leather choices but won't confuse you all now

Agreed
Chrome leather can't be wet formed but does come in a variety of colours . In saying that it does have it place being more suitable for wet conditions.
for example if you wear leather boots your wearing Chromed leather most leather garments these days are chromed it has it place both in price and functionality.
But again it can't be wet formed and is not tooling leather, it also is said not to be good with metals like knife blades ( not sure about modern chrome technics bit then again it can't be formed so why make sheaths)
