They offer it in the shallow, mid-depth and deep 6 point socket sets and in 12 point sets. A total of 10 different sets offer it. It's in every set I cited plus three more. So because they sell some sets that do not offer it, you'd skip buying the sets that do and go to another brand? Makes no sense to me.
Using that rationale, Snap On skips the 4 and 4.5mm socket in some of their sets - so you'd go to another manufacturer in that case also even though they offer it in other sets. To each his own I guess.
It does make sense to Me, because ProTo and SnapOn are My favored tool brands.. Also, Mr SnapOn usually says: "no problem". SK, Duro, and Craftsman have been purchased over the years much as a matter of convenience to backup My most frequently used tools. With USA Craftsman and Duro(long) out of the picture; that left SK, till they crashed.
The SK tools were once sold in a local hardware store; where I could walk in and look them over. Sk had some crappy years; and not every eBay seller will state whether the set they are selling is new stock or leftover stock from crappy years. It certainly doesn't help matters when eBay sellers include three pages of jabber in their ads, and don't list the sizes of the sockets in the set.
Current SK sets of 1/4" drive flex sockets perk My interest. Acme Tools in Grand Forks, ND stocked SK tools before the SK crash.. I plan on stopping there while in GF tomorrow and see if/what they have in SK stock. I will hopefully have a chance to look over the current production flex sockets. If I like what I see, and it's a reasonable price; I may buy them. No hurry.. I should mention the Current SK production has one of, if not THE most impressive 1/4" drive socket assortments I have viewed.
You can have crappy salesmanship, or total lack of salesmanship sink the sale of a good product. I recall ONE SnapOn dealer some years ago. He was one of the most arrogant humanoids I have ever met, so I avoided him.
I consider some of the SK peddlers in the same humanoid camp as that SnapOn dealer.. I did e-mail one eBay seller today; asking the socket sizes in a set... Do these people think we don't care? I was curious as to how long it will take to respond... Well, it couldn't be any worse than the Craftsman site a few years back, where i got no response after several tries..... Or calling SnapOn customer service and asking for the phone number of our area dealer. I was told our area did not have an area dealer.. Being I had met the SnapOn truck numerous times while driving, I contacted an area Auto Dealership I worked for years back, and inquired there.. I was given The SnapOn Dealers phone number and called Him.. Arrangements were made to meet the following week at one of his regular stops.. In the meantime;;;;;; a few days later;;;; I called SnapOn customer service a second time. The phone was answered by the same crabby woman; and I asked her the same question as before. Again I was told there was no area dealer serving our area.. I enjoyed informing her that I had contacted our Area Dealer, and would be meeting up with Him in Erskine on Thursday.. Then I asked "would you like His name and phone number"?? After a moment of silence, she grumbled a response.. I told her I called out of respect for any other customers who are also trying to contact our SnapOn Dealer.. The Young Dealer was a friendly, businesslike person.. I bought some tools, and had three ratchets repaired.. I told Him about the crabby woman. I believe she was another member of the humanoid camp I mentioned earlier..
ProTo, SnapOn, and SK are My three prime tool choices..
As mentioned;Poor salesmanship can sour My purchase of any of the three.
I usually have two quality options during those times.
Being SK is #3 on My list, it is not big deal for Me to bump them.
