It'll get better with time!
   Real men dont use box cutters tho,they use a table saw and try to stop the blade!
 Get yourself a small ball and squeeze it all the time,when your hand can!  I used a ball of wax,Charlei Bronson taught me that trick in his movie "The Mechanic"!
  I was told I would never be able to make a fist again and I would be lucky if all my fingers would even bend. I saw the surgeon about 6 months post OP and he said make a fist,which I did and he was amazed!!!  Then he proceeded to ask all sorts of question,grabbed 2 of his colleges and got out a book with pix of my hand to show them. I didnt look..... 
 
 
 But they all asked how I did this and I pulled my little ball of wax out of my pocket and showed them. It's now a part of standard therapy,they have different sizes and hardnesses but I just used regular candle wax and made a ping pong sized ball.
  Good luck and remember if it's all itchy,thats good the nerves are healing!!!!
