Is purpleheart right for your knife? Choose it when you want colour in the handle: a purple wood that slowly darkens towards brown, with straight, even grain that stays calm on an octagonal shape. It suits a black or marbled horn ferrule and a single ring metal. If you want a handle that never changes colour, choose a dark wood instead.
Purpleheart at a glance
- Species: Horn & Grain’s catalogue declares its Purpleheart as Peltogyne spp., a genus rather than a single species. That is the catalogue’s declaration, not supplier or batch evidence for an individual blank.
- Look: CIRAD’s Tropix sheet gives purple as the colour reference, a medium texture and straight grain with no interlocked grain, and notes that the purple wood turns dark brown with light.
- Density and hardness: Tropix gives an average specific gravity of 0.87 and a Monnin hardness of 7.6 at 12% moisture. The Wood Database lists a Janka hardness of 2,520 lbf (11,190 N) for Peltogyne spp.
- Trade rules: Tropix records purpleheart as not listed in the CITES Appendices, and a search of the CITES Checklist for Peltogyne returns no listing. Rules can change and depend on species, product and destination, so check the current listing before shipping wood across borders.
- Price: Purpleheart sits in the configurator’s Standard tier, shown at $55 for a mid-size build with a black horn ferrule (captured 26 October 2026). A marbled horn ferrule adds $5.
- Handle length: it follows the knife, not the wood. Our wa handle size guide starts Compact at about 105–115 mm, Mid-size 115–125 mm, Chef 125–135 mm and Long 140–150 mm and over, and calls these starting ranges, not ceilings.
How purpleheart looks, and how it ages
The Wood Database describes the change in three steps: freshly cut heartwood can be a dull greyish or purplish brown, it becomes a deeper eggplant purple within a few days of exposure, and with further age and UV light it turns dark brown with a hint of purple. A UV-inhibiting finish can slow that shift, but light keeps working on it. Expect a new handle to read brighter than one that has spent years in the light.
The grain is usually straight and even, so the colour, not the figure, does the talking. On an octagonal handle each face catches the light a little differently, so judge the colour from more than one photo.
Ferrule and rings
We build our purpleheart designs for harmony rather than contrast: one ring metal per handle, an end cap that matches the ferrule, and only a few rings. White nickel suits the cool purple, so our current purpleheart designs use white nickel rings with black or marbled buffalo horn. The simplest has a black horn ferrule and no rings at all, which is the quietest version and lets the colour carry the handle.
Caring for a purpleheart handle
Wipe the handle after washing, dry the ferrule joint, and keep the knife out of the dishwasher and standing water. Ask which finish is on the handle before applying oil or wax, and keep the knife out of strong sunlight when it is not in use if you want the purple to last longer. Oil is not a repair for movement or a gap at the ferrule.
Fit and measurement
Keep a secure installed handle installed. Close side and spine photographs of its junction can show accessible height, thickness, alignment, and condition, but they are partial observations rather than hidden tang dimensions. If the tang is already exposed, record exactly three primary dimensions in millimetres: usable shoulder- or seating-line-to-tip length, near-shoulder height, and face-to-face thickness at that same station.
Use the configurator to choose the wood, ferrule, shape, and size. Measurements and photographs are optional before purchase and can be added or corrected on the order page after payment until bench work starts.
