Erasable pens don't often make my daily rotation, but when one does it is guaranteed to be a Pilot FriXion. Other companies have tried to compete with Pilot in this realm but none have come close. When you think erasable pen all you need to think about is FriXion.
The Pilot FriXion Ball Knock Biz Gel Ink Pen is the latest to come across my desk, from my friends at JetPens of course, and it it may be the best barrel yet. It falls in their high end FriXion line, like the Biz Point 0.4 mm, and others, before it.
The metal Ball Knock Biz barrel has a great weight to it and the retractability of the tip (using the clip as the knock) is a huge plus. From a design standpoint, the only thing that may take it down a notch is that you have to unscrew a cap at the end of the barrel to get to the eraser. Several other models leave it exposed for quick access. Otherwose, it is a very sharp looking pen.
For those who are not fans of the FriXion line the issue with the pen always comes down to the same thing: The gel ink colors are too light compared to their non-erasable counterparts. I agree with this, but I am willing to pay that price for erasability. The black ink is my least favorite, so I keep the blue 0.4 mm needle tip refills handy, which I enjoy. Yes, the ink is lighter than traditional blue gel inks but this one works for me.
For $33 the Ball Knock Biz does not come cheap. If you are a fan of the FriXion line it may be worth the barrel upgrade to you. If you are wanting to test out a FriXion to see what the fuss is all about I would recommend going with the standard Ball Knock retractable (reviewed here). Regardless, Pilot has the erasable pen market on lock down and the FriXion is the only model in this category you should consider.
