Great review
I guess I will deal with the sheath
So the Granfather is a solid knife to use in the field?
What is the full curve blade of the Grandfather like to use?
The grandfather knife I have is an older, rat-tail version. It held up really nicely for years and years, only recently has the blade started to rattle a little. Something that could be fixed, Im sure, but the knife has so much sentimental value nowadays that I decided to retire it (a great excuse to buy another knife too!).
Ive used the knife for light battoning (the blade is pretty short, so heavy battoning isnt even possible), cleaning a few fish, carving all sorts of past time projects, making a ton of fuzz sticks and for all sorts of camp chores. The orginal sheath was lost years ago, so I made a grude leather sheath which worked nicely enough.
About the full curve, I havent experienced any problems with it with the type of work I needed the knife for. The knife is perfect size for carving, and the wide blade makes it possible to choke on the blade for really detailed work.
I often carry a knife in my jacket pocket rather than on my belt, so one reason I like the knife so much is the compact size. It has been enough for my trips, though I have to admit that I rarely build natural shelters or huge fires (ones that require cutting down trees, dead or alive), not even during winter time, so I have little use for a big knife .
Edit: I just noticed that you intend to pair this knife up with an axe and a saw. For that kind of use, I think the grandfather would be a good choice. I think it mostly depends wether or not you like the bigger handle (compared to the carpenter) and if youre willing to pay the higher price of a Roselli. Personally I think there might be puukkos out there with similar quality but a lower price, but then again especially the grandfather is a unique design, and there isnt really another knife that looks like it.
