Using a knife blade for shaving Magnesium block and striking the flint rod would dull the edge fast, so I am not very keen to use my existing blade. The broken saw blade that come with the magnesium block usually rust after sometime in storage, which I would dispose of.
So I am wondering about the possiblitiy of using a Titanium prybaby for shaving the Magnesium block and striking the flint. Maybe a little modification to one side of the prybaby such as saw teeth would do the trick.
What do you think ?
