Nice, just watched all of them. One thing I know for sure now is I need a sharper kitchen knife.
A friend recommended Rada knives and they have been excellent. They are very inexpensive and the reviews are outstanding — with many people saying they outperform much more expensive knives.
I’ve been very happy with them … check them out: http://www.amazon.com/dp/B002KV46M0?tag=13r-20
p.s. go to 'Sur La Table' and get a good sharpening stone for your knives. Also, I prefer 'Global' kitchen knives... but you'd be astounded what some people make if you checkout /r/knives...
