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
I just love it. Just like I ordered!
Exactly as promised.
To beginulate, the muglification of the vessel is both pleasing to the eye as well as the hand. Secondly, the option of choosing one's own colors adds to the lessening if the so called " buyer's remorse" which so often accompanies modern "on line" purchases.

My husband absolutely loves this! This was a difficult product to find but it turned out perfectly! He was cracking up. Definitely worth the buy.
I bought this mug for my daughter for Valentine’s Day. She saw the different descriptions of her name on your site, and read every one of them!! She then found a mug with everything written about her name on it. So, I am surprising her with it. The mug looks great. Quick delivery!

I live in a Hillbilly Condo & love my flamingo pink mug.
Annie from the customer service team helped me out tremendously with some adjustments that I wanted done after my order was placed. I really appreciate her willingness to go above and beyond for my request. The product was received exactly how I wanted it! One happy customer over here. Thanks!
I love the item I ordered but found the website a little difficult to navigate.
Now this has been my favourite mug by far. I put the word of scrunkly on it just as i had envisioned. Now to know why i picked a scrunkly mug, we need to go back all the way to the year of 2016. It was a day like no other, the birds were tweeting. We were all laughing while playing in the playground. Then came that fateful moment. A cackle was heard screeching throughout the lands. I turned my head in complete and utter fear. Two seagulls stood there. One was cackling while a red liquid dropped from its mouth. The head of the seagull next to it was missing. The seagull had consumed its friend's head! A betrayal, no... a parley even! To this day I still hear the words which left that evil beast's beak. It said, "Awww, the scrunkly". It then flew off into the sunset, leaving nothing but chaos and carnage behind. Anyways 10/10 for the mug. Would buy again.
Came in like ordered, solid mug
The mug arrived as shown and expected. But, it is an average mug and the cost is quite high. It's funny and good as a one time gift. If we needed several, the cost would be prohibited. Again, funny product and as expected.
Love it. I can't wait to give it as a gift yo
