i'd take the real knife, aesthetics aside.
Some are but lots are marked HC for high carbon.
Both look good. I love a good knife. If I had to pick one it would be the spike cause I've got lots of normal steel knives and don't have any spike knives. Really want to make one some day.

Another "high carbon" misconception involves railroad spikes. Nearly every bladesmith has made knives from railroad spikes. Railroad spikes are readily available, usually for free, they are a novel item, and they can make a perfectly useable knife. However, they simply do not contain enough carbon to make a good blade. One big misunderstanding comes from railroad spikes that are marked "HC" for "High Carbon". The problem is that what the railroads consider "High Carbon" is equivalent to what a knifemaker would call low carbon mild steel.
According to specifications set forth by American Railway Engineering Association there are two classes of railroad spikes, low carbon track spikes used on straight sections of railroads and high carbon steel track spikes used on curves and switches. According to the specifications, low carbon spikes may contain no more than 0.12% carbon and "High Carbon" spikes may contain NO MORE THAN 0.30% carbon.
Knife blade steels typically contain between 0.85% and 1.5% carbon, or 3-5 times as much carbon as a "High Carbon" railroad spike.
The reasoning is that the railroads want mild steel that will bend rather than break. A bent spike will still hold a rail whereas a broken spike will not.
