Don't top chefs recommend and use carbon blades? My sabatier chefs blade is carbon, has a glorious patina and no rust. My mora only showed signs of corrosion after I forgot to clean it after cutting Choc caramel shortbread and even then soon cleaned up with wire wool - 000 grade - and honing oil, and was as good as new. I personally prefer carbon to stainless for everything except canoe rescue knives as they tend to look better, seem to sharpen easier (or is that just my bias?) and "feel" better. The carbon Moras are cheap, look great (especially re-handled and vinegar treated, and with a new sheath all afordable "first projects" as the Moras are so inexpensive) and do the biz.
When re handling I use the "Henry rabbet" or rebated 2 piece handle system, generally carving end rebating the wood using another Mora bladed knife!
I love these knives, though I do have (many) others.
Remember folks, not only Frosts produce knives in Mora, E Jonsson, amongst others do as well and you can get Mora laminated carbon blades cheap as well - if you know where to look!
The Frosts green plastic handled, carbon steel bladed knife is still a real winner and well worth the dosh!
