grind
1. Hollow ground—A common grind where a convex hollow is removed from both sides of the edge. It produces a very sharp edge but being so thin the edge is more prone to rolling or damage than other grinds. It is unsuited to heavy chopping or cutting hard materials. Straight razors are hollow ground. This grind is used extensively in mass produced knives. 2. Flat ground—The blade tapers all the way from the spine to the edge from both sides. A lot of metal is removed from the blade and is thus more difficult to grind, one factor that limits its commercial use. It sacrifices edge durability in favor of more sharpness. The Finnish puukko is an example of a flat ground knife. A true, flat ground knife having only a single bevel is somewhat of a rarity. 3. Sabre ground—Similar to a flat ground blade except that the bevel starts at about the middle of the blade, not the spine. It produces a more lasting edge at the expense of some cutting ability and is typical of kitchen knives. 4. Chisel ground—As on a chisel, only one side is ground (often at an edge angle of about 20 – 30°) whilst the other remains flat all the way to the spine. As many Japanese culinary knives tend to be chisel ground they are often sharper than a typical double bevelled Western culinary knife. (A chisel grind has only a single edge angle. If a double bevel has the same edge angle as a chisel grind, it still has two edges and thus has twice the included angle.) Knives which are chisel ground come in left and right-handed varieties, depending upon which side is ground. 5. Double bevel or compound bevel—A back bevel, similar to a sabre or flat grind, is put on the blade behind the edge bevel (the bevel which is the foremost cutting surface). This back bevel keeps the section of blade behind the edge thinner which improves cutting ability. Being less acute at the edge than a single bevel, sharpness is sacrificed for resilience: such a grind is much less prone to chipping or rolling than a single bevel blade. In practice, double bevels are common in a variety of edge angles and back bevel angles. 6. Convex ground—Rather than tapering with straight lines to the edge, the taper is curved, though in the opposite manner to a hollow grind. Such a shape keeps a lot of metal behind the edge making for a stronger edge while still allowing a good degree of sharpness. This grind can be used on axes and is sometimes called an axe grind. As the angle of the taper is constantly changing this type of grind requires some degree of skill to reproduce on a flat stone. Convex blades usually need to be made from thicker stock than other blades. It is possible to combine grinds or produce other variations. For example, some blades may be flat ground for much of the blade but be convex ground towards the edge.
The Urban Dictionary Mug
My daughter is a Seinfeld afficianato. She was pleasantly surprised when she opened the package with her Penske File mug. It has the definition of Penske File from the Urban dictionary. Totally worth the price!
gay mug very spicy
The Urban Dictionary is a unique place to find anecdotal memories on all sorts of stuff. Their ongoing communication once your order is placed is excellent. I have put in a significant number of orders recently, and the communication regarding my order status is excellent. I have had one order misplaced in transit. They have contacted me to say that they will get back to me, but to this point, they have not. So, that's a bit of a caveat in my rating. Overall, I would rate their products and customer service as good. I would not hesitate to deal with them in the future. Fill Your Boots with Whatever You Want to Order. Nice job, "Urban Dictionary."
Thank you for sharing this Unique piece of Artwork. You are the only one that offered this. Thank you for the quality service you have provided not only in what you offer but right on to the quality packaging as well. Thanks again - Peggy Hall
My brother Tom became an uncle & urban dictionary created a wonderful uncle Tom mug…
It is special to have a mug that has to do with my dad who invented a word when we were growing up. He passed away last year. Drinking from this mug is like spending time with him.

Quick turnaround time and good quality merchandise.
very cool kanye for me gave it to my crush and now were dating so yea
I bought a Prone mug and i love it its so good imma prone to the bathroom now brb
This mug gives my life purpose. It's what I've always said. Patience is a virtue and hard work never betrays. Ever since I was born I've been struck with one misfortune after another, but today it all paid off. I got my own mug, and I use it anywhere and whenever I can! Both of my legs are shattered because to my wife threw me in the middle of traffic and my windpipe is messed up due to me screaming all the way from the crash site to the hospital thanks to the unbearable pain I was feeling. Although even with all that's happened this is still the best day of my life. I suppose the only problem I have is that whenever I happen to look at my cup I get a little too happy. That causes problems because my life support can't handle my exhilaration, haha! I'm just kidding; that was just a little lighthearted joke of mine. I actually cannot afford life support because I spent all of my life savings on this fine piece of pottery. Not to worry though! I can get through the pain with my will and drugs - I mean medication. P.S. There are definitely no ghosts in the mugs. Just wanted to point that out in case someone was worried about that.
I bought two mugs as gifts for coworkers and they were very pleased. The print was clear and concise. Hopefully they last a long time.
Ordered a gift for a friend I hope he likes it :)
Mug was well-packed when received. Shipping was timely. The mug was as advertised. Very nice.

It's perfect!! Thank you!
My Name is Walter Hardwell White, My Mug was sent to 308 Negra Aroyal Lane, AQ, New Mexico and arrived on-time and I am very satisfied. My "Glock Dookie" mug is great for my lab work, and my friend Pinkman loves it!
I love this cup! My now ex-husband loves his opioids more than life itself. He would constantly pass out dead to the world the only thing I would here was his death moans. I had to call an aid car for him so many time that I can't remember plus 2 or 3 times the doctors told me that if it wasn't for me, he would have died. Her abandoned me after I was diagnosed with ovarian cancer because I was of no use to him any longer. I have no clue now who must be the one that's obligated to save his life any longer. All I know is I'm free from him now. The only thing I'm waiting for is that he finally overdoses himself & he's dead. I am buying a cup to send to him for our divorce anniversary gift so he can keep it in memory of how he treated me.
