When I was searching for a reliable mechanical pencil, the Ohto MS01 caught my eye. After using it extensively, I want to share my experience and some key points to consider if you’re thinking about buying one too.
Design and Build Quality
From the moment I held the Ohto MS01, its sleek metal body impressed me. It feels sturdy and well-balanced in my hand, which is essential for long writing or drawing sessions. The pencil has a minimalist aesthetic that I really appreciate — no unnecessary bulk, just a clean and professional look.
Writing Experience
The 0.5mm lead size offers a smooth and precise writing experience. I found the lead to be consistent without frequent breakage, which can be a problem with some mechanical pencils. The pencil glides comfortably over paper, making it great for both note-taking and sketching.
Lead Advancement Mechanism
One of the standout features for me was the twist mechanism to advance the lead. It’s simple and reliable, unlike click mechanisms that sometimes jam. This twist system also helps protect the lead when not in use, preventing it from accidental breakage.
Comfort and Ergonomics
The grip area is metal but not slippery, giving me good control without discomfort. Though it doesn’t have a rubber grip, I didn’t experience any hand fatigue even after extended use. If you prefer softer grips, this might be something to consider, but I personally liked the solid feel.
Refill and Maintenance
Refilling the lead is straightforward — just unscrew the tip section. I appreciated that the pencil uses standard 0.5mm leads, so finding refills is easy and affordable. The eraser is hidden under the cap, which is a neat feature, though it’s small and better for minor corrections.
Value for Money
Compared to other metal mechanical pencils I’ve tried, the Ohto MS01 offers great value. It’s durable, stylish, and performs well without a premium price tag. If you want a pencil that looks good on your desk and works reliably, this is a solid choice.
Who Should Buy the Ohto MS01?

Final Thoughts
Overall, my experience with the Ohto MS01 mechanical pencil has been very positive. It’s become my go-to pencil for everyday tasks. If you value build quality and a smooth writing experience, this pencil won’t disappoint. Just keep in mind the lack of a rubber grip if that’s important to you.
