I think it's quite possible to understand it and still find it pointless or useless.
Personally, I don't think the benefits of blades outweigh the negatives in regards to amateur golfers. The actual amount of control and shot shaping ability that you gain with blades over a player's iron is minimal compared to the forgiveness that you gain with a player's iron. I'm not saying that a player's iron is forgiving, but you gain more forgiveness with a player's iron than you gain in control/shot-shaping with a blade.
As an amateur that has played blades and player's irons, I have yet to hit a shot with a blade that I couldn't have hit with a player's iron. I have also never stood over a shot with a player's iron and thought "man, I sure wish I had a blade for this shot." I have however, stood over shots and been glad that I didn't have a blade in my hand.
Blades are not the most forgiving and if your not the best ball striker they may not feel the best, also when hitting range balls they tend not to feel the greatest. Where as pros on the range don't use range balls... and they have fewer miss hits. But the best thing to do would be to go and try out clubs, then go from there.
