Time to post some more knife pics, got a day off, will get some more stuff up soon. About the 01/L6, knife is great, takes a nice refined edge, have been finishing it at 8k. Seems to be nice for a line slicer, has no problems with duck breasts or crispy chicken skin, it's super thin so it likes to glide right through items. It is definitely better as a protein slicer than an all around prep knife, although it can do double duty, it definitely likes proteins over veg.
It glides through root veg though, squash, sweet potato, rutabaga and celeriac are very easy with this thin guy, also lateral cuts on onions are easy, although pull chopping onions has an odd feel. Then you switch to push cutting onions, and realize this just isn't the knife for onions, it will do it, because you need some onions and this is on your board, but it's not the best.
I really really like the slim handle for slicing, maybe that's why it doesn't feel like the best veg prep knife, like I said, you can do it all with this knife. I really like the edge the knife gets, but it doesn't last incredibly long, and doesn't respond well to a ceramic. I can't wait to get my strop from Marko because I believe with this knife, and the felt strop will be a godsend for this knife. I personally work way too many hours on the line a week to be sharpening that much, and I have slicers that respond well to my ceramic between sharpenings and I must say, they take over after this guy has lost it's fullness, until it's sharpened again, then it's my #1.
So I would say the steel is a nice steel, that takes a good edge but loses it, I would consider quickly. Others may have different experience using 01/L6 dammy and this is just my personal experience, like I said I am really dying to get my strop from Marko because I believe it will really bring this knife to the top of the pile. In comparison my Fowler pictured earlier in 52100 doesn't get nearly as sharp, but is almost always workably sharp (ya I know some guys just can't do this). It responds to a bite with a few passes on a rod, I sharpen it maybe once a month when its just dead from the rod. So I alternate between the two on the line between sharpenings, does the job, if I have a busy night I will get the Mario sharpened up, or for the weekend.
In summary, I highly suggest contacting Mario, and if you like he has the exact shape of this knife sitting around somewhere. It's 244mm on the edge, 40mm tall at the spine, and has a great little relieved choil area that your middle finger rests in like no other knife I have. Super cool knife.
