Original Goat 80/20.5 with Thicker Custom Scales: Does Extra Handle Thickness Perfect the Design?

Introduction

About a month and a half back, a simple request was made to Original Goat: build a custom set of 80/20.5 scales that are just a little thicker than the stock ones. The goal was not a redesign, just a nicer hand feel from extra handle dimension. The result arrived practically flawless, paired with an aluminum back spacer, and after assembly the verdict is clear: this thickness genuinely improves an already well-liked knife.

What Makes These Scales Different

The stock Original Goat 80/20.5 scales and these custom ones share the same overall design, but the custom set is substantially thicker. The exact dimensional difference is not specified, but the effect on hand feel is immediate and very positive. The thicker slabs fill the hand in a way the thinner scales do not.

There is a trade-off worth acknowledging. The thinner handles have a real benefit for carriability, since a slimmer knife pockets more easily. But purely from an ergonomic standpoint, the thicker version wins. In fact, with the extra thickness and this blade shape, the two configurations now feel like completely different knives.

Installation Notes and One Small Hiccup

Assembly went smoothly overall, with one small issue found during installation. The holes cut for the stays are almost exactly the size of the stays themselves. They fit most of the way in, but at the very end there was slight resistance. Once pressed down, a small piece of aluminum, a tiny tab sticking out of each hole, clicked free and everything then seated smoothly with no further problems.

The classic challenge with the 80/20 and 80/20.5 remains the spring, and losing track of it somewhere in the room is a real risk, so keep assembly off a garage floor. One genuinely helpful tip: sliding back the locking mechanism allows the pivot to drop straight through all of the liners. That made assembly much easier than in past builds.

Everyday Carry Impressions

A Lynch Northwest deep carry pocket clip was fitted for testing. It definitely rides deeper in the pocket, which is its main selling point. However, the feel of the original clip is still preferred, so the deep carry option may come down to personal priority: maximum pocket depth versus a more familiar in-hand feel.

Part of that preference may relate to the handle material itself. If these thicker scales were titanium rather than aluminum, the deep carry clip might feel more at home. That said, the aluminum back spacer is a clear visual upgrade over the plastic spacer, and it also changes the sound of the knife in a pleasing way.

Is Thicker Better Here?

Having handled an 80/20 previously, the extra-thick 80/20.5 feels a lot closer to the ergonomics of that knife. The combination of thick scales and this blade shape comes across as beyond gorgeous, and it is tempting to imagine this same thickness executed in titanium.

Real talk: the thinner scales are nice to have and better for carry profile, but the thicker set arguably perfects the 80/20.5. The extra bit of hand feel is definitely worth it, and these are expected to appear on the Original Goat website eventually, where they will likely find an enthusiastic audience.

Buying Advice

For anyone ordering or waiting on these thicker 80/20.5 scales, a few practical takeaways: expect a near-flawless finish, be prepared for the snug stay holes during install, and use the locking mechanism trick to drop the pivot through easily. If you value ergonomics over the slimmest possible carry profile, the thicker scales are the version to choose. And if titanium ever becomes an option at this thickness, that would be one to watch closely.

Conclusion

The custom thicker scales and aluminum back spacer transform the Original Goat 80/20.5 into what feels like a different, and arguably better, knife. The ergonomics improve noticeably, the aluminum spacer looks and sounds better than plastic, and the only trade-off is a slightly bulkier carry. For fans of this platform, the extra thickness looks like the definitive take.
