Balisong knife, a uncommon street knife, or collector's star. The model is relatively high polygonal, if necessary it is possible to make a 3D print. If necessary, make a different texture, or prepare for printing. The model itself consists of - a blade, two handles, washers, fasteners, pins on the blade, handle pins. I am a fan of blacksmithing, so the model has a solid texture, made of different metals.
Resolution - 1024, 2048, 4096. Cards - BaseColor, IOR, Metalik, Normal, Roughness.Metals - Bronze; Damascus; Titanium; Brass; Thungsten; (At least that's how I see them...)
I got a nice experience, and used the existing experience. I enjoyed the work, and didn't spend much time. Although, a lot of unnecessary geometry could be removed, simplified. But if necessary, it will be done...
