It’s perfectly integrated into the clip so that it can be discreetly hidden and accessed. More than just a money clip, Gerber decided to include a fine-edged stainless steel blade measuring 1.75 inches. IT has a cool G-10 front plate and features anodized aluminum accents. Made of titanium coated steel and rust proof materials, this top money clip can hold up to five credit cards and features a large engraveable surface. The Gerber GDC Money Clip lives up to the name by serving as one of the sleekest money clips you can buy that’s also a good price. However, there is a wide variation in that small range.Gerber has been providing some of the best knives and tools since 1939. In general, good knife steels will have an HRC number anywhere between the high 50s to low 60s because that’s the sweet spot for most steels. Now comes the tricky part: Deciphering what the HRC number means for your knife and how it will affect performance. For example, Crucible Industries says CPM S30V steel has an ideal hardness of 58-61 HRC and gives knifemakers the different responses to heat treatment temperatures. In some cases, you can find the recommended heat treatment and the hardness you should aim for. The hardness of a blade is also affected by the heat treatment. On the flip side, steels with low hardness can result in rolled edges.Įach steel has its own optimum level of hardness - between where it’s too weak and too brittle. Steels with extremely high hardness become brittle and prone to chipping. For example, materials like concrete and glass are extremely hard, but since they are not malleable at all, they can break far easier. It’s easy to assume that a higher number is better because it’s stronger, but that’s not always the case. A low HRC number means the steel is softer and a higher number means it’s harder. So now that you know how it’s tested, what does the number actually mean? The HRC - which also goes by other abbreviations like RC - lets you know the hardness of the steel. Rockwell testing can leave a mark on the steel, which is why many makers measure it on a part of the steel that’s concealed by the handle. Here is a quick video talking about the measuring process. It’s pressed into the steel at two levels of pressure and then the numbers are measured before calculating the results into the HRC via a formula. To find the value, a diamond-tipped cone is impressed into the steel to measure the depth of the indentation. (HRC means Hardness on Rockwell scale C.) There are several different scales by which a material’s hardness is measured on, but blade steels are measured on the C scale. The Rockwell scale was cocreated by Hugh and Stanley Rockwell in the early 20th century to test the hardness of different materials. What is the Rockwell Scale?Ī blade’s hardness is based on the Rockwell scale. Understanding the Rockwell hardness is not the most intuitive thing out there, but with a little information, you can be more informed about the characteristics and performance of your knife. But if you don’t know what it actually means for your knife, you’re not alone. You may know that it represents the hardness of a blade or even that it is measured on the Rockwell scale. If you’ve bought a knife in the past, you’ve undoubtedly seen something like “HRC 56-58” in the specs.
