Appearance: The DM03 is an attractive pencil with very clean lines. The bright yellow body has black imprinting which is very legible. The lead grade indicator is knurled and at the top of the body. The lead grade indicator window is rectangular showing the silver over gloss black lead grades which are H, 2H, 4H, 2B, B, HB and F. The bright chrome push button is the full over-sleeve type, which fully hides the chrome eraser holder. The bright chrome pocket clip rests below the lead grade indicator and is stamped with the country of origin, Japan. The chrome grip is nicely knurled in a diamond pattern and steps down twice to form the integral end cap/lead sleeve, squaring off before becoming the lead sleeve. The end cap/body coupler is seen only as a ring between the grip and the body.
Disassembly: Complete take down of the DM03 is not quite as simple as with other pencils and is NOT recommended. To fill the lead reservoir first remove the chrome push button, then the eraser from the reservoir tube. Drop in a few pieces of lead the put the eraser... Awe, come on! You know the rest! If you have to clear a lead jam you will have to remove the grip. Simply unscrew the grip and slide it off the end of the pencil.
Clearing A Lead Jam: Refer to this article, Clearing A Lead Jam, should clearing a lead jam be necessary. The link is on the front page of this blog.
My Opinion (for what it's worth): The Alvin is a heavyweight of a pencil with its balancing point being 82.5mm from the top of the pencil. This makes the Alvin bottom heavy, which helps it rest comfortably in my hand. The finely knurled diamond pattern on the chromed grip affords my fingers a good hold. Both features help make writing with the Alvin a delight to write with, it almost writes for me. Three clicks of the push button produces enough lead to write or draw with, a comfortable 1 mm. The lead reservoir is not cavernous, being small in diameter, but it will hold a couple of dozen leads. The lead grade indicator at the top of the body spins to freely and can move during normal handling. The bright silver characters of the lead grades are set against a gloss black background making them hard to read due to glare. However the push button can be replaced and the eraser used without causing lead projection.
Last Words: The Alvin Draft/Matic DM03 was designed as a drafting tool but serves well as a freehand drawing tool or as a fine writing instrument. Its balance and feel make it suitable for anyone who wishes to use it in either respect. So if you are in the market for a high quality writing or drawing tool keep the Alvin DM03 in mind as you shop.
