These are shipped raw, without oiling or other treatment, and have the AO2 logo laser etched at the base of one end. The wood grain is visible in this state, but not highly pronounced. They will play very well straight out of the box, and will gradually darken over time as the wood picks up oil and moisture from the player's hands. Those wishing to accelerate this process can rub in a dab of any kitchen oil, beeswax, or other similar non-toxic wood product. The logos are shallow-etched--they have texture and can be felt, but should not chip or feel uncomfortable. Like the grain of the wood, the logos will darken over time.
Please understand that because these are made from a natural material, they will vary in appearance. Some are darker, some are lighter. Some have more pronounced grain patterns, and others have very little. This is particularly the case with the ebony and purple heart wood pieces, which have a wild range of patterns. Some have very distinct colour patters with sharp contrasts, and some are completely uniform in colour. Please understand the we cannot accommodate special requests in this regard. In addition, because these are turned on a wood lathe, there may be light markings or lathe lines on the wood. Any kbones with chips or splinters that might affect the feel or playability have been sorted out during our quality control process, but most of the kbones will have some visible discolouration or blemishes on close inspection. These are character marks, and if you're using your kbones a lot, they are certainly not going to be the last character marks. If you are uncomfortable with this, or if you want a much more precision-controlled item, we recommend the delrin models as a good alternative to the wood.
Please note that all wood versions are indeed made of wood, and have all the beauty, charm, and the vulnerabilities of wood. When dropped on rough surfaces, or if kept in pockets with sharp items like toothed keys, they may chip or scratch. That said, the wood versions are light enough that when they do drop, the impact is not very hard, and as such, they tend not to do much damage to themselves.
Note from the designer: I developed the original knucklebone circa 1989 when I was a kid in school. The crude original version was made from some kind of polymer clay (see photo). The new version is better suited to bigger hands, and has been designed for smoother flow and better trick potential.
Warnings: Some versions are heavy and solid--can break things or hurt things if dropped. It is recommended that you play over carpet, couch, or the like, or outside. Some versions look almost tasty, so keep them away from young kids, and don't let anyone try to ingest them.
