![]() Even though these can be pigmented with color, they will still Patina dramatically over time. A combination tanned leather that undergoes at least 89 separate processes taking 28 working days.Ī corrected grain leather with dramatic pull-up and soft waxy feel. Types of Corrected Grain LeatherĬhromexcel is a trademark tanning process from the Horween Leather Company. It's a weak argument, and in my experience, I haven’t found any durability issues with corrected grain. Some folks consider corrected grain less durable than full-grain because of the sanding during the correcting process. It also means that patina can take a longer time to develop and there’s less breathability compared to full grain. This means the leather can be easier to clean and doesn’t absorb as many oils and moisture. The burnishing operation on Chromexcel prepares the leather for finishing by opening up the grain and allowing the stains to penetrate the leather.ĭuring this corrective process, the pores of the leather are sealed. This allows Horween to hand-stain the leather. Snuffed Suede leather is heavily corrected to create a Nu-Buk effect (heavy tracking) whereas Chromexcel is “corrected”, through a process that is more of a burnishing operation. Two examples are Horween's Snuffed Suede leather and Chromexcel. Many big manufacturers (especially in apparel and footwear) cannot have cosmetic variances in their products – therefore they choose top grain leathers for quality, but also to have a consistent appearance in their leather goods. In a nutshell, tanneries will remove “imperfections” or add varying degrees of corrections to achieve a desired look or functionality. So how is Corrected Grain leather different than Full Grain leather? This is the same section where full-grain is split. ![]() It simply means that this leather is from the top cut of the hide when it is split. People can confuse the "top grain" and "full-grain" leather grades as different splits of leather, but according to John Culliton from Horween: "top grain can be either a full-grain leather or corrected grain leather." Noticeably absent in this diagram is Bonded Leather - an abhorrent concoction of leather slurry I will cover later. You can see where each leather grade comes from when the cowhide is split. Take a look at this cross-section of a cowhide.
