It is probably mild steel and not really the best for knife blades.
Try striking sparks, using an angle grinder or bench grinder is easiest as it gives you a plume of sparks to watch.

Tom, Just bought my first knife making steel from these guys http://www.knifebargains.co.uk/acatalog/01_Tool_Steel_Knife_Making_Blade_Blanks.html#a7595
Cost me 16 quid for 50cm piece of 4mm 01 carbon knife making steel - no spark test required! It came within two days and am really looking forward to getting to work on it.
Bad luck with your high ropes course offcuts - they looked like perfect knife blanks!
Cheers,
T

Hi Tom,
As has been pointed out it is more than likely that those are made from mild steel. However if you are new to the knife making game then use this as practice steel.
You will need to grind or file it to shape first but be careful if you should choose to attempt a heat treatment as the steel looks galvanised to me. Heating galvanised steel causes zinc fumes which are deadly poisonous.
Once you feel more comfortable with shaping your blade, buy in a known steel like the 01 linked above. 01 is generally regarded a good place to start as it is a fairly simple high carbon steel that is quite forgiving.
All the best

It looks like it might be galvanized. If so you don't want to heat it too much as the fumes can make you really sick. If you really want to use salvaged steel old files are a fair bet.
Hello mate,
It is 99% mild steel but you can try it - heat it to nonmagnetic (cherry red
) and quench - if it is hardened after that you can give it a try and if not just use it for tests as another mate in here suggested ;0
