I wish I had a camera capable of up/downloading to my computer...oh well, more $$$ spent from my pension!
Take a pen/pencil. Hold it against the 2nd set of knuckles (palm side). Close your fingers around the pen/pencil, kind of like a karate-chop position.
That's how I position the scales against my hand.
Where are your lead finger and thumb in relation to the blade's heel?
