I used two cylinders for the hilt guards but I pretty much just traces the rest of the hilt by extruding a vertex around the reference image (tracing it).
Reference:
I only used the solidify modifier, but as expected, it didn't help much. I'm still very new to Blender so I'm sure there is something out there I haven't found yet.
I'd also appreciate it if you have any tutorials you'd like to suggest for problems like. (It's not an easily youtubable title to find a solution for)
