Nice video Allen,I gave my unscaled tin knife away for my 1000th post giveaway,but still have my scaled one.
You might try holding the knife right above the shavings & pulling the rod towards you.There's less chance of you disturbing the shavings that way & the sparks are more concentrated towards them also.Just my 2 cents.
Happy New Year BTW!

It's better to have it & not need it than to need it & not have it! (a gun that is)
May the forest be with you.
