I am a fan of Olfa cutters since 20 years, however don't have many and rather low cost. Have also NT-cutter which is of excellent quality, not only handle but also very smooth sliding. And KTC-Murata, but here some cheap DYI stuff. I don't think NT-Cutters are better than Olfa due to better plastic - in both cases it is usually standard ABS, where you don't recognize the difference. It is more complexed if we take 2-component handles (hard plastic+elastomer) or anti-slip soft touch polymer. I believe NT Cutter is more common in handles made of cast Al. My NT-cutter's handle is made of cast Al.
I have also nice, handy, small Olfa knife. It is really sharp. And it is ok for my small hands.
At the end auto-retractable - I found it - no idea who is the producer - the difference to Olfa SK-4 is 6 ribs (instead of 4) and slightly different color. And no logo nor any writing. Maybe just a copy of Olfa. And Olfa blade fits perfectly well.
