Spyderco Shaman DLC Marks: Rubber Sharpening Guides Leave Their Trace and r/knives Has Answers
A brand-new knife with marks on the coating is every owner's worst nightmare — unless the marks are your own fault and entirely removable. That is the situation an r/knives member found himself in this week with a Spyderco Shaman he just acquired and absolutely loves. The marks in question came from rubber angle guides on his sharpening stone, and he wanted to know whether they could be taken out of the DLC coating without damaging it.
The Shaman is Spyderco's burly compression-lock folder, and DLC — diamond-like carbon — is the black coating of choice across the industry for its hardness and corrosion resistance. But DLC is not indestructible, and one of its lesser-known quirks is exactly what happened here: soft rubber can leave faint transfer marks or light rubs on the coating when it presses against the blade during sharpening. The marks look alarming but are usually superficial, sitting on the surface rather than in the coating itself.
The thread delivered the standard toolkit of remedies, and the consensus was reassuring. Most commenters recommended starting with the mildest option — a gentle wipe with a soft cloth or a pencil eraser, which often lifts rubber transfer marks without any abrasive contact. For stubborn marks, a dab of oil on a microfiber cloth or a light pass with a coating-safe polish was the next step up, with the universal warning to avoid anything aggressive that could wear through the DLC and expose bare steel.
Beyond the fix, the thread doubled as a sharpening PSA: rubber angle guides are great for keeping a consistent bevel, but they sit against the blade coating while you work, and a little care — or a barrier between guide and blade — prevents the scare entirely. Several members shared their own DLC maintenance routines, turning a worried question into a genuinely useful resource.
The poster's closing note that he loves the knife regardless is the right attitude — a surface mark from sharpening is a badge of use, not a defect. And thanks to the thread, his Shaman should be back to flawless black in a few minutes of gentle work.
