Habermas 2075: A Harness Leather Briefcase Built Like a Tank

Most of my briefcases are made to look refined. The 2075 is not, and that is the point of it. I built it in the summer of 2024 from very thick harness leather by the Hermann Oak tannery, and I left it thick on purpose, because I like how it behaves when it is hard to kill.

Leather that scratches on purpose

Harness leather is thick steer leather made for horse harness, and it is a different animal from the English bridle I use on most Habermas bags. It is stiff and it is heavy. It scratches easily, and it patinas fast, in months, where bridle takes years. Once the bag is carried and brought out in the sun, it starts to change, and I think that change is the best part of owning one.

The journal article comparing bridle and harness leather sets the two side by side. The page on leather choice covers Hermann Oak, a tannery with more than 130 years of experience, and the piece on bridle versus vegetable tanned leather explains why both age the way they do.

Why the inside is left bare

I almost never line a harness briefcase. The outside is going to pick up scratches and scuffs, and a suede lining under that would be a refined interior behind a beaten exterior, which has never worked for me. Unlined, the inside is matted down and smooth, and if something spills in it, you wipe it away. The inside is as rustic as the outside.

The natural leather lining page describes how I finish the back of the hide on the bridle bags.

The same latch, on heavier leather

The 2075 carries my classic Marcellino latch, a solid brass latch I developed for lawyers who wanted to open a bag quickly without a buckle. Harness leather suits it. The bag is built with a double gusset and rings on top for the shoulder strap, and the handle is the traditional one I have been making for years.

The latch has a loop that keeps it from moving when the bag is empty. The loop is removable, and a client who always packs the case full will never need it. The page on high-end locks covers the other closings I build.

How long it lasts

I think a harness briefcase gets ten to twenty years of good use, and I mean carried and used, not kept on a shelf. That is an estimate from my own bench, and I give it as one. I abused a roughly ten year old harness test case for the video where I unpacked a fresh Hermann Oak side. It had been oiled and baked in the sun, and it shows exactly how this leather ages.

Harness is one of the first leathers I built briefcases from, so I came back to it with some history. It makes a heavy bag, and I accept the weight in exchange for a case that behaves like a tank.

Stitched like the rest

Every seam on the 2075 is saddle stitched by hand, the same as every other Habermas. The page on hand stitching and the article on saddle stitch versus machine lockstitch explain why I work this way, and why a hand stitch holds on leather this thick.

Looking after it

Harness leather is vegetable tanned, so it takes conditioner or oil, and the leather care page gives the routine. The journal article on caring for a bridle leather briefcase adds the habits that apply to a waxed leather.
