Has anyone purchased one of theses yet? If so what are your thoughts? I’ve been hoping to snag one on the secondary market but ain’t seen one pop up yet.

I have a Guppy in Magnacut. The blade is a 10, ergos are a 10, handle construction is an 8. Not bad, but the handle is a little simple in terms of machining. There isn’t any weight relief other than the cutout for the insert, and the bearings run on straight titanium.

.....and the bearings run on straight titanium.

Is that an issue?

Is that an issue?

Frankly, I think probably not. Except I’ve seen a couple of ZTs (also straight ti) with brinelling damage from overtightening. I just don’t understand why a maker wouldn’t take that extra step to put in steel washers.

brinelling damage

Thank you. I learned something new today.

From Wikipedia:

"Brinelling /ˈbrɪnəlɪŋ/ is the permanent indentation of a hard surface. It is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force, and the depth and diameter of the mark indicates the Brinell hardness of the surface. Brinelling is permanent plastic deformation of a surface, and usually occurs while two surfaces in contact are stationary (such as rolling elements and the raceway of a bearings) and the material yield strength has been exceeded.

Brinelling is undesirable, as the parts often mate with other parts in very close proximity. The very small indentations can quickly lead to improper operation, such as chattering or excess vibration, which in turn can accelerate other forms of wear, such as spalling and ultimately, failure of the bearing."
