Generally the lower end companies will use a steel for fixed blades that is softer because it means that even though you loose edge retention you gain a lot of toughness. Even today there are probably 10x the number of fixed blades made with 1095 than any other steel. And that is because it is simple and comparatively soft. So yes it needs to be touched up more often than say, S90V, or even CPM-154, but it has much more toughness that allows you to beat on it and it won’t chip out, or crack.
Now, 440C isn’t a super hard steel, but it can go semi brittle if its treated to to topmost limits of its hardness. So why take the chance, use a steel that is easily and cheaply HT’ed to 55 or so and just don’t worry about it.
Yeah, Ganzo definitely included a thumb disk:
Then we have the ones on the right with the elongated opening for the axis lock to slide in - characterisic of older Ganzos.
I want the 749 more and more, it’s a good design. Regardless of any competition between brands, it would be good to know who made that design.
Those are good if you live in the US or CAD, the shipping costs to Europe make this rather useless.
Also it’s quite difficult for us metric folks to find out what the heck of a size such a screw would be in Imperial Standard and usaknifemaker.com states clearly that they won’t find out for you what screw you need.
I don’t really like that particular Ganzo, so I’m not really searching for screws atm. Too many other projects in the pipeline
I’m sure that there are similar in the UK or Europe. I know there are custom knife makers there so there must be places to buy supplies.
Even an electronics place will likely have screws that fit.
And we Canadians use the metric system too. lol
