Of course I cannot access the full text article, but the claim that this HW can be sharpened and become "3 times sharper" than "most commercial table knives" sounds not very scientific.
- moron4hire 5y agoSharpness can be quantified, and most table cutlery is probably made from 420 stainless steel. Not a particularly great steel, but very common.
- tgsovlerkhgsel 5y agoSince "table knife" means the typical dull cutlery knives (as opposed to e.g. steak or kitchen knives), I have no doubt that wood (hardened or not) can be sharpened like that.
- ummonk 5y agoYeah I suspect they're comparing to cutlery knives out of the box - without any extra sharpening.
- jaclaz 5y agoNot only, a "good" knife can be measured by its sharpness (and still the 3x sounds very little scientific) but also by the durability of its sharpness, there is a a youtube channel[0] by a guy that makes blades out of "everything" and they are actually sharp, but how much do they last (and last sharp enough) is unsaid, and in the end of the citation it seems like they propose these HW knife as a replacement for plastic cutlery. [0] as an example only a knife made out of plastic bottle material (should be PE): https://www.youtube.com/watch?v=3ZnT31JeBTg https://www.youtube.com/watch?v=3ZnT31JeBTg
- ummonk 5y agoYeah, and with a Brinell hardness of just 31 I doubt knives made out of this material would hold an edge that well.
