I'd like to see specific comparisons in physical properties versus steel and specifically which steel they are comparing to. Including in physical dimensions since their nail seems fairly thick. Steel is, as I understand it, hundreds of different variants each with their own physical properties.
For example, they say 23 times harder in the article than regular wood. Wood has a Brinell scale of up to 7 although most is less. Times 23 that comes out to 161. Mild steel is 120. However hardened tool steel is 900.
- klyrs 5y agoIt's safe to assume that they're comparing to mild steel, which nails and table knives are made from. That said, I'm amused by the thought of a hardened tool steel nail... make sure you wear safety glasses and gloves, because when that shatters, the shards will be sharp and speedy. Here's hoping it's the nail, and not your hammer.
- mdpye 5y agoI had some questions about that too. It looks cool, to be sure, but I watched the video of the nail being hammered through some boards, and... let's just say I'm not so timid with steel nails! For what they were showing, if you were going for "equivalent to steel", I'd expect to see a tap to secure the nail and then probably only two strokes to sink it. They tap it a hundred times, which begs the question of what would happen if you actually hit it. Strength comes in many dimensions.

LIGNOLOC wooden nails are shot in pneumatically [using their specific nail-gun with reels of their nails]. LIGNOLOC wooden nails conserve tools and saw blades when post-processing wooden components in prefabricated buildings. LIGNOLOC wooden nails do not cause any unattractive wood discolouration or leave any traces of corrosion, such as those left by steel nails. LIGNOLOC wooden nails do not act as thermal bridges. This results in better insulation values and improved structural properties.
