The Old Geezer
Please Excuse My Absence

I have not blogged since July of 2015 due to the fact that my Lovely Wife was diagnosed with 2 types of cancer. A new case of breast cancer which has metastasized and gone to her bones, mainly her back. She had a mastectomy of her left breast which showed the type of cancer that was in her bones. She has been taking an oral med. every day and she has a port under her skin to receive a liquid med. She has gone through one round of radiation treatments to stop some pain in her back. That gave her GERD and the med for that was nasty tasting. The bone cancer has caused the vertebra in her lower back to pinch her left sciatic nerve causing her pain, numbness and foot drag. She also has skin cancer that has only been partly addressed.

I have been busy taking care of her as the treatments have left her weak and sickly. She can not drive so I have to drive her to her appointments and treatments. I also have to do all the cooking and most of what cleaning we do. So I do not have a lot of time for blogging. However the installment of the review of the Schaeffer Ultrafine 0.3mm pencil marks what I hope will be a new review every month. However some of my future reviews may seem familiar as they may be a review of a pencil or pen that I have reviewed before just in another size due to my limited collection of writing instruments and the economic state of our nation.

I am grateful to George Fox for wanting me to do a review of another one of his pencils. I think that as a reader of my humble blog, may fine of interest as the Schaeffer Ultra Fine is a very unusual pencil.

So please excuse my absence and as a reader of my humble blog I hope that you enjoy the review of this unique pencil.

Coming Soon...

Thank you,

The Old Geezer.

Koh-I-Noor Rapidomatic 5633 0.3mm Automatic Pencil

Hello Pen And Pencils Blog Fans... and other assorted strangers!  Welcome to my humble blog and another riveting review!... OK, so maybe not so riveting, but a review none the less!  I did this one for Associated Content a couple of years ago.  It's in a style I no longer use, but, hey, it's a valid review no matter what Tommy Turquoise says!  I've altered it here for my blog.  Enjoy!


Technical Data:
Length: 142.1mm
Diameter (Body) 9.1mm
Diameter (Grip): 8.1mm
Balance Point (From Bush Button): 74.6mm
Weight: 17 grams
Lead Sleeve: 4mm, fixed
Lead Size: 0.3mm

Major Components: End cap/lead sleeve/grip, body with lead grade indicator, pocket clip, clutch assembly/lead reservoir, push button and eraser with clean out rod.

Construction Type: Independent body and clutch/lead reservoir.

Construction Materials: Plastic body, metal end cap/lead sleeve/grip, pocket clip, push button, clutch assembly and lead reservoir.

Colors: Red, body, bright chrome pocket clip, lead grade indicator, push button, end cap/lead sleeve/grip, lead reservoir.

Mode Of Operation: Ratcheting push button lead advance, 3-jawed brass clutch with brass over-sleeve.

Appearance: The bright red color of the hexagonal body with its white lettering makes a striking contrast against the bright chrome of the other components. The chrome lead grade indicator rests at the top of the body and is finely knurled. The silver lead grade characters are set against a gloss black background and include the grades H, 2H, 4H, 2B, B, HB and F. The chrome pocket clip sets just below the lead grade indicator and is embossed with the brand name and country of origin, Japan. The chrome push button is the full over-sleeve type completely covering the lead reservoir and has the lead size nicely embossed on the top. The chrome grip is nicely knurled in a diamond pattern and steps down twice to form the integral end cap, squaring off before becoming the lead sleeve.

Disassembly: To completely disassemble the 5633 first remove the grip. The clutch assembly and lead reservoir will probably come along with it. Remove the clutch assembly from the end cap. Remove the pushbutton to expose the eraser. Remove the eraser to access the clean out rod. This completes the disassembly of the 5633. Reassembly is the opposite of disassembly.

Clearing A Lead Jam: Refer to this article, "All Jammed Up?", should clearing a lead jam be necessary.

My Opinion: The Koh-I-Noor was designed as a professionals tool but it's equally at home on the desk of the average homeowner. It is a well designed and built, being a highly sought after pencil brand for years. The lead is rock solid in the lead sleeve with very little if any wobble. Three clicks of the push button produce 1 mm of lead, quite enough lead to write with. Any more and there is a risk of breakage. The chrome lead reservoir is cavernous enough to hold several tubes of lead and still have room to spare. This is a feature that I like as I like to fill the lead reservoir with as much lead as possible. The balance point of the pencil is almost at the midpoint so the pencil is only slightly bottom heavy but it doesn't feel like it. The finely knurled diamond pattern on the grip makes a good surface to hold onto and helps guide the pencil across the paper. The only thing I don't like is the lead grade indicator. I'm not fond of the top of the body type of lead grade indicators. The one on the Koh-I-Noor started out tight but after years of use it has loosened up. Also the silver characters are set against a gloss black background making them hard to read due to glare. However the 5633 is a great pencil to write with being finely crafted and well built. I like the Koh-I-Noor, it feels good in my hand and is an easily guided across the paper despite its 17 gram weight, or maybe because of it. Either way I like this German designed pencil and wish that I had more.

Last Words: The above review was of a pencil that I've had for years. It was made in Japan and is a very well built pencil, possibly as well built as the original Koh-I-Noors made in Germany. Unfortunately the line is now made in China. The Chinese version of the pencils are not quite up to the standard of the Japanese or German versions. It's for this reason that I can not recommend buying a Koh-I-Noor 5633 unless you can find one in new or good condition that was made in Japan or Germany.
