TWSBI Precision Mechanical Pencil Review

Most people know TWSBI for their ever-expanding line of fountain pens, but did you know they make ballpoint pens and mechanical pencils too? I found it to be an interesting decision when TWSBI first introduced these items, but as I have come to expect from them they have created a high quality, fairly priced product.

The model I received for review from JetPens is the TWSBI Precision Mechanical Pencil 0.5 mm with retractable tip. It is a full metal body pencil with a nice knurled-style grip, and a tip that retracts when pressing down on it and clicking the mechanism. It's a nice feature, although not one that is make or break for me personally. What is interesting though is that the retractable tip models are the exact same price ($25) as the fixed tip models. That is not something you see from other vendors. The retractable tip usually costs a premium.

Writing with the Precision is a nice experience. It is well balanced, the knurling is tame, and the provided lead of unknown origin is smooth, dark, and not too soft. The eraser is one of the niceset I have used on a mechanical pencil, removing all traces of graphite easily and cleanly. And it is extra long, so it is far more useful than it's competition. TWSBI also ships extra leads and erasers with the pencil, which is a great bonus.

If you are a mechanical pencil fan, the comparisons to the Rotring 600 are inevitable. The TWSBI Precision is less expensive and has the added retractable tip option, but the Rotring 600 is widely considered to be one of the best drafting pencils ever made. There is something about its feel that is solid and dense, yet its light enough to allow you to glide across the page without knowing the pencil is there.

So yes, gun to my head I take the Rotring 600 over the TWSBI Precision, but that's just me. The TWSBI is excellent in its own right, and fits in nicely with its competition in this price range. I look forward to seeing what else TWSBI has up their sleeve in the non-fountain pen realm.

Pentel Graph Gear 800 Drafting Pencil Review

Like micro-tip gel ink pens, mechanical pencils are a tool I like to have handy everywhere I may be writing. There is something about their technical design and fine lines that speak to me, and the Pentel Graph Gear 800 is a nice addition to my lineup.

Pentel’s Graph Gear lineup is well known and widely respected. The 1000 model drafting pencil and ballpoint are hugely popular with their aluminum barrel construction, but there is a definite place for the plastic barrel of the 800 lineup. The key is in the grip. It is metal, giving it the proper weight and balance for a drafting pencil, and features the same rubber pads that give other Graph Gear models an excellent feel.

Pentel color codes their barrels to match lead diameters, with black for 0.5 mm, blue for 0.7 mm, and yellow for 0.9 mm (green is 0.4 mm and brown is 0.3 mm for those product lines that use them). This is helpful for professionals who may have a lineup of pencils on their table when having to switch up line widths.

I find using the Graph Gear 800 to be a real pleasure. It is a comfortable writer while retaining the solid feel of the twice as expensive 1000 model. I prefer it over the less expensive Pentel Sharp model as well. The grip alone is worth the added cost.

Overall, this is a quality drafting pencil that I’m happy to have at my desk.

Zebra DelGuard 0.5 mm Mehanical Pencil Review

The Zebra DelGuard introduces a new lead breakage prevention mechanism to the market by absorbing some of the writing pressure within the internals of the pencil. As with all new products on the market that introduce new features, it boils down to does it work as intended. In the case of the DelGuard, it does.

When I first saw the DelGuard I assumed by the similar looks that Zebra was going for a Kuru Toga type mechanism, but that is not the case. Instead, they built in cushioning inside barrel in the form of a spring and lead pipe that adjusts as you write.

My concern with the DelGuard is that I would feel the mechanism working as I was writing, but that wasn't the case at all. I prefer firm mechanical pencils and it felt as if I was writing with any standard pencil. That's good design. Do your job while not interfering with the expected experience.

I'm a medium to heavy pressure writer and never once broke the lead writing normally. When I increased my writing pressure gradually the lead stayed intact as well. Of course you could push it to the breaking point with extreme pressure or extending the lead too far, but the DelGuard handles everything else admirably.

If you enjoy mechanical pencils and lead breakage is holding you back, then give the Zebra DelGuard a try. At $7.50 it's not exactly cheap but if it can eliminate frustration it may be worth it.
