Stainless Steel vs. Carbon Steel Tools
Introduction
Many beginners and experienced practitioners as well as bonsai, often in a dilemma when it comes time between steel (black) to choose tools that are usually more expensive or shiny stainless steel appliances.
I have always maintained that a better and more economical to purchase quality equipment with high-quality steel more than stainless steel that is equal or more expensive. But the debate will always rage on.
Marty Weiser, a practitioner of Metallurgy and Bonsai, offers the following discussion the difference between stainless steel and carbon, so that your own opinions.

What is stainless steel?
Generally stainless steel (SS) with the addition of at least 10% chromium (Cr) with iron. SS then form an oxide of chromium oxide surface mounted, SS and prevent further corrosion. This material is locked into the body-centered cubic ferrite phase (BCC) and strong enough and not very durable.
Nickel (Ni) is often added to the SS to change the structure of the austenite phase is much more resilient and improve resistance to oxidation at high temperatures. One of the common value of SS with 18% Cr and 8% Ni and is used in everything from industrial pipes for the spoon and fork. In the U.S., this is known as Type 303 or 304 SS.
The role of carbon in steel
Carbon steel is often added to increase hardness. Adding as little as 0.5% carbon can make a big difference in the hardness of steel. However, increased violence comes at a cost of much less elastic. Viewing control that allows heat treatment to control the trade off between hardness and toughness - but if you make a mistake, you can end up with a knife that will not continue to destroy the edge or if he fell. Very high quality Japanese steel tools often laminated piece of high ductility, low carbon steel thin body for low ductility steels with high carbon content with hard-edged knife and very elastic.
cast iron is listed with 2 to 5% of carbon is usually too fragile to make a good cutter. However, they make incredible machine tools, because they are very stable.
The problem with carbon steel
However, we discussed the SS If you are looking for the definition of steel, you'll find something along the lines of "iron-carbon alloy with more than 0.1%." Are you looking for the composition of the SS, the most you will find that the carbon content of less than 0.1%. Therefore, non-technical steel SS. Why SS carbon content is limited? Well, if you each heat treatment combined with carbon, such as with chromium, chromium carbide with the formula, Cr23C6 form. This forms a compound along the grain boundaries (not specified) and confiscated along the grain boundary Cr. However, Cr had to make corrosion-resistant material, so that when you remove the SS does not rust. Therefore, the concentration of carbon-limited SS.
So the SS does not contain much carbon, to ensure that it remains free of rust. What were the results? Now responsible for the production of carbon steel harder so they have a very nice sophisticated place. Therefore, the SS is not too hard and make a bad cutting tools. Well, not really. Metallurgists to imagine that a good metal and steel will hold a decent big demand, so they are some of the SS who developed quite advanced. In the U.S. it is 400 series SS is important is that by careful control of composition and heat treatment you can use a metal which is a good compromise between hardness and corrosion resistance to create. However, you make a mistake in a well you end up with material that is too hard (brittle) or too soft (not to stand up and tip). Generally inexpensive tools such as knives SS error in a soft side, while high-quality products that is right or wrong is usually on the side too hard.
