This one's been with me for 11 years now and it will likely be sharp long after I'm not.
Here, I had just gone through a bunch of stuff for a big batch of chili.
The acidic juices from the tomatoes etched it quickly, but any sort of patina never stays after splitting a few logs.
It's big and heavy, but it's my goto around the yard and car camping.
This one was made in Nepal by Anil from Himalayan Imports. Bought it around 2012 from Auntie Yangdu.
