The pen is beautiful and stable. Its length is rather short, but it fits my hands (size 10) perfectly. Because of its greater thickness I love writing with it. The Fisher Space Pen refills don't really fit well, because they can't be extended without adjustment (filing or re-drilling). Not so bad for me, since I use gel leads in standard G2 format. The Fisher Space Pen refills have a thickening at the front shaft, which is probably not standard.
Not compatible with Fisher Space Pen Refill
I bought this specifically because multiple sites claimed it to be compatible with Fisher Space Pen refills. It is not. The opening in the point of the pen is too small to allow the Fisher refill to protrude so the bolt action can function. Given that I bought it (from SMKW) primarily for this compatibility, I count this as money wasted. I tried multiple Fisher cartridges, both refills and original cartridges from my own EDC Space Pens with no luck. I can only assume that Boker's mfg tolerances have drifted over time or their QC is lacking.
