If I was to write a review about these it would say: "Sickening rubbish: if you are anti-knife crime, do not buy!"
I spotted Red or Dead co-founder Wayne Hemingway and his other half Gerardine had one in a photo of their kitchen carried in Hello! magazine last year (like the one inset on this knife crime post).
It is baffling why prominent people, such as these trendy / fashion-conscious partners - with huge fashion design credentials - would own such offensive crap. (You may recall Wayne Hemingway recently moved the Vintage Festival event from Chichester / Goodwood to London, unsuccessfully apparently; here's another example of poor judgement then.)
When this knife crime blog first started, I remember highlighting how people in the fashion industry have some kind of sick love affair with violence, stabbing, death, knives, guns etc. Do you recall the post? You can read it again here (about an Italian fashion house... must be something in the sick mafia blood over there): Boycott Dolce & Gabbana over idiot knife adverts. Think D&G removed the ad (thank goodness!) but the BBC report is still live and explains all and the ASA ban on this horrendous advert is still accessible. Wonder how many more fashionista idiots abound... let me know!
In any event, let's have the anti-knife crime campaigners get these voodoo 'blade blocks' banned, let's have retailers remove them from shop shelves and online stores stop stocking them. At the very least we need to embarrass (odd!) people, such as the Hemingway's, buying them. If you bought one by accident, just bin it (try metal recycling perhaps, pop it in at one of the world's police stations, or drop it off in a local knife amnesty bucket somewhere).
