Okay, I'll give my two bits here on this one. In the Mandalorian language, the word "Beskad" means "Iron saber". Now, teeeeechnically, the word for saber,
kad, is used as a reference to anything of sword size, i.e. not a knife or small blade, that has an edge, whether for hacking or cutting. Traditionally, in the English language, the word Saber refers to a sword, usually curved, with a single edge that is used for cutting and hacking, usually from horseback but not always. So, arguably, a beskad
could refer to a machete type weapon
or a katana type weapon, it really just depends on who forged the weapon. Also, keep in mind I'm going off of semantics, verbage, interpreted language, and common sense of the technical variety here, so canon may contradict me. In which case, usually it's better off to refer to canon.
Moving on to the original question of sharpness, it depends on the blade. A machete uses the weight of the blade, the inertia of the swing, and the user's muscle strength to cut. Think a cutlass. It's not so much to slice and dice and sever limbs as it is to break bones or hack into armor. Katanas are used to slice and cut and are effective against most armor types short of heavy, metal armor like platemail (though a short blade that looks like a Katana is actually referred to as a Wakizashi). Obviously, a weapon meant to cut and slice will need to be sharper than a weapon designed to hack and chop, so frequency of sharpening and keenness of the blade will be more precise for cutting blades as opposed to chopping blades.
Beskar is also a tough metal and has, in canon, resisted everything from blaster bolts, bullets, lightsabers, and I vaguely remember a reference that it took a turbolaser the face, but don't quote me on that last one as I don't remember fully enough if that was actual canon or ambiguous canon or if I misread something. So, arguably, beskar wouldn't need to be sharpened as often depending on the blade type, but in that same breath, sharpening a super hard metal is going to be a massive pain in the rear even with electrical and/or machining equipment.
Welp, hope that answers your question. If not, @ me and I'll see what else I can do to help
