Sun-Star Knock Free Sharp Mechanical Pencil - 0.7 mm - Yellow

Its cute and fun to use but sometimes I found it did get scratchy when using it. I usually ending up pulling the lead out a bit more than what was advanced by itself. It was annoying because if the lead didn't advance once it had gotten shorter I had to take it apart and put in a new piece of lead to push it forward and then put the new lead back in the container since there was no room for more than 1 piece of full sized lead.

I found mine got jammed with pencil lead and would stop advancing. Its a pain in the but to clear jammed leads as I found it difficult to remove the brown "wooden" part of the pencil from the advancing mechanism without breaking it. Pushing something in through the black sleeve doesn't work and will make the situation worse!

Kind of a let down. Though I love that no one can really tell its a mechanical pencil. Also it would be nice to have eraser refills/replacements

I love this pencil. When I got it, I got a big piece of paper and just started scribbling until the lead ran out. I wanted to see how well it advanced and if it got scratchy. The lead advanced so well I couldn't tell when it did. It did not ever get scratchy. If I held the pen at a very shallow angle, it did scratch a little, but I hold it about 45 degrees.
Refilling was no more difficult than any other pen. I just dropped a lead in the end and pressed on the black tip a few times and it was ready to go.

If this technology was in a normal pencil with a clip and autoloading magazine like the Pentel Quick Dock and hey, how about the lead-breakage preventing technology of the Millino or the Platinum OleEnu, Then pencil lovers could stop fussing and get back to writing the great american novel.

Putting Lead Through the Front is NOT Possible! (as stated by description)

I just bought one and took me a few minutes to figure it out. I wanted to use blue lead instead of graphite so I bought some 0.7 Blue Eno lead from Pilot also sold in Jet Pens. I will use it for some preliminary draws before I ink or draw on top of. My review is to facilitate people who want to change the leads. It's not as easy as regular mechanical pencils, but it's not too bad. First you have to pull out the lead from the from by pushing back on the grey plastic tip that is suppose to look like the tip of a pencil. The you can pull the lead, but nice and slowly always retracting from the place it's coming out and not simply pulling from the end out (that will snap the lead). The you twist off the eraser holder (not eraser) until you pull out the container that is filled with extra lead (2). I removed them and the one the pencil came with and stored it for another mechanical pencil later. I grabbed the blue leads and unlike how it states you put by the front it's not possible. You can only add 1 lead through the inside. You have to let it slide in the hole (you can see it) and then you basically begin to draw on a scrap piece of paper until it comes out. If you do this for less than a minute it will come out. Once it starts drawing you can simply pull the lead out and pushing the pencil tip in a little to desired length and you are set.

1. You refill the lead by unscrewing the ferrule and taking a lead out of the container and putting it into the barrel. With the cap back on the lead container, put the pencil back together and the containers concave tip will push the lead into the holder.

2. I don't find this scratchy at all and don't have a mental hangup about seeing a mm of lead sticking out. My gripe is that it only comes in 0.7mm. I'm used to using the Kuro Toga 0.5 that rotates the lead. This pencil is for a thick, casual line, for large note taking, this isn't for something you'd give to someone else. I love the look and will buy more if they get a 0.5 or smaller.

cute pencil. The only problem for me is that the lead in the front is too short, but this doesn't cause real problem in writing and it's not scratchy.
