Knives.
A good knife makes all the difference when you are cooking.
There are a number of sites out there that offer great knives. They are not cheap but worth the investment as taken care of, they will last a lifetime.
I've been going to Japanese Chefs Knife for probably about 10 years. They have a large selection over a wide price range. Their service is fast and prompt and delivery is great without any import or duty issues.
Since I eat steak alot, a good steak knife is important to me.
I was at a steak house in Chicago a number of years back and really like their steak knives. They are made in France and are excellent quality and are the Laguiole brand. A set of 6 will set you back around 560 Euros so they are not cheap.
Over time, I lost a couple of them and also found they were hard to sharpen given their serated edge. So I was looking for a new set when I came around the company of Salter Fine Cutlery. They make high end knives that are all handmade in Hawaii by a family run business. The actual blades are again handmade in Japan. Their quality and service are amazing. Since they only do small batches at a time, you need to contact them and detail what you want. The knives in the picture are the ones they made for me. I couldn't be happier!
