Lately I’ve been spending a lot of time on the Straight Razor Forums, and for the first time I’m consistently getting excellent results from my razors. A special thanks goes out to JimmyHAD from SRP for helping me along the way.

My sharpening background comes from working on reed knives, kitchen knives, scissors, and even dental instruments. Because of that experience, I naturally gravitated toward progressive sharpening. When using Shapton stones, the approach feels especially logical because the system is designed around moving through increasingly finer grits, all the way up to 30,000 grit if desired.

The theory behind progressive sharpening is straightforward. Each finer stone replaces the scratch pattern from the previous stone with a denser and more refined pattern. As the progression continues, the scratches become increasingly uniform until the bevel develops a mirror-like finish and a highly refined edge. For example, you might establish the bevel with a coarse stone such as a 320 or 1K, then progress through 2K, 5K, 8K, 15K, and finally finish on a 30K stone. The end result is an extremely fine edge with a scratch pattern measured in fractions of a micron.

Recently, however, I’ve become increasingly interested in pyramid sharpening. In a previous article, I described how the pyramid method focuses on removing the high points left by the previous stone rather than simply replacing one scratch pattern with another. The goal is to smooth out the peaks and valleys created during sharpening, resulting in a more even cutting edge.

Using the same progression as before, the practical finishing stone in a pyramid sequence may actually be the 15K. The 30K stone is then used only for a few light finishing strokes to smooth and level the surface left behind by the 15K rather than creating an entirely new scratch pattern.

This is where the comparison becomes interesting.

In my opinion, the path you take to reach your second-to-last stone is not especially important. Whether you use a progressive sequence or a pyramid sequence, you’ll eventually arrive at a highly refined edge. The pyramid method may take a bit longer because it requires moving back and forth between stones, but that’s a relatively minor consideration.

The real difference lies in the final stages.

With pyramid sharpening, the last few strokes on the finishing stone are intended to reduce the peaks left by the previous grit, effectively leaving behind a smoother version of that earlier finish. With progressive sharpening, the goal is to create a true finish from the final stone itself. On paper, a fully developed 30K edge sounds superior.

The challenge is that it is very easy to overwork the finishing stone. Too many passes on a 30K stone can eventually create its own microscopic peaks and valleys. While these irregularities are much smaller than those left by a 15K stone, they still exist. In contrast, the pyramid method may leave an edge that is technically less refined but smoother and more consistent.

After thinking about it for a while, I’ve come to a simple conclusion:

Neither method is universally better.

As with most sharpening discussions, the correct answer is usually, “It depends.”

The pyramid method offers a margin of safety because it reduces the risk of overworking the finishing stone. It tends to produce a smooth, forgiving edge with less chance of creating unnecessary micro-serrations. Progressive sharpening, on the other hand, is perfectly capable of producing outstanding results when performed carefully.

An experienced sharpener can easily adapt the progressive method by limiting the number of finishing strokes on the highest grit stone. In fact, this is where the two approaches begin to overlap. Many sharpeners effectively borrow concepts from the pyramid method by using only a handful of finishing passes after their second-to-last stone.

Ultimately, both techniques can produce excellent shaving edges. They simply approach the same goal from different directions.

So which method should you choose?

Whichever one gives you the results you’re looking for.

In the end, debating progressive versus pyramid sharpening may be a lot like arguing about Coke versus Pepsi. Both work, both have loyal supporters, and sometimes the best choice is simply whichever one happens to suit you best that day.
