At the 2013 Winter Wonder Festival in Tokyo Japan, a cheap but unique "butt pencil sharpener" was introduced. This can be considered the most NSFW pencil sharpener out there.
Recently, Tokyo had held its 2013 Wonder Festival which is held twice a year with the first one held during the winter season and the second held during the summer season. This is a twice a year event to attend if you are a huge fan of anime and/or video games. This is where you go to buy or sell your “garage kits” which are assembly scale model kits of just about anything and everything. If you are one that buy video game and/or anime-related merchandise, then you should be familiar with what garage kits are.
One of the things that could get the attention of most people, which only costs about $5.40 a piece, is this special pencil sharpener called an “oshiri enpitsu kezuri.” In Japanese, it's a “butt pencil sharpener.” Simply put, you insert a pencil into the “butt” area to sharpen your pencil. Keep in mind that there are quite a number of these “novelty” pencil sharpeners out on the market; but, there's probably none in the market like the one introduced at the recently held Tokyo Wonder Festival.
This special butt pencil sharpener is definitely not safe for work (NSFW). Bring that one to school, you'd probably get a detention or a suspension. Bring that one to work, you'd probably get slapped with a sexual harassment charge. RocketNews24 reports on this special pencil sharpener which was unveiled at the Wonder Festival. There's nothing sophisticated about the pencil sharpener; it's mainly a small stiff board that shows the backside of an attractive anime female on all fours with the side of her face turned in your direction. She's naked which means her bare bottom is visible.
The special butt-shaped pencil sharpener gets attacked to where the bare bottom in. Then, you put your pencil inside and sharpen it. In short, this “pornographic” pencil sharpener doesn't leave much to the imagination. This can be a good aide for sexual foreplay. It is one of the most “unique” simple pencil sharpeners that Japan has to offer. For that that decide to get one of those pencil sharpeners, the only thing to imagine is which “opening” is the pencil getting inserted into.
