I just ordered a Zero Tolerance ZT 0220. It came out about 4 years ago and I have always wanted one. I think it was discontinued sometime in 2020 and all of the regular online retailers had shown them as discontinued and not available. The only ones on ebay were selling for the introductory price or used. For about a year or so you could find one for about $50-$60 less than that. I broke my bag of searchfu managed to find one website with them for the discounted price.

Order is in. This is my second time ordering one and the last time the dealer got kind of screwy. I had to file a claim on them and it kind of soured me on buying the knife. I think this is a good first purchase for 2021.
