Horween Cxl Vs Veg-Tan Strength?

[Acceptable]

I'm looking to make some slim wallet/credit card holders with ~4 oz leathers.

Can anyone comment on the strength and durability of 4 oz Horween CXL vs 4 oz Hermann Oak or W&C Bridle leathers?

Under regular use, is there any discernible difference between the above leathers when it comes to durability? I'm primarily worried about the sharp edges of plastic credit cards potentially cutting through the suede/flesh side of the leathers.

There will be no discernible difference in durability whatsoever for your purposes. Credit cards will not cut through Chromexcel. It stretches far more than bridle, but it's incredibly durable and perfectly suited for pouches and sleeves.

Considering the sharpening lengths people go through to get a steel knife sharp enough to cut quality leather, i think you will be fine with credit cards. The crappy leather most consumer grade items are made out of is a different story. Stitching, Now that can be cut by card, and ripped by over-filling the wallet. Design and stitching is the key to durability in a wallet. It is also the biggest part of the cost. The leather cost is small compared to labour and material cost to construct a wallet, especially if hand stitching. I have seen tenfold more leather goods fail at the stitches than i have seen the leather fail.
