"The ERU is definitely an item to watch, and it is poised to redefine the pull though sharpener and carbide plates for sharpening in general."

"I had participated in the original product testing of this device, and the improvements from the prototype are good. If you go where a set of stones or a belt grinder isn't going to be available, this will be the thing to take."

"Additionally, it will be just the right tool to touch up an edge during game dressing or filleting fish anywhere. I think the non-knifemaker folks can finally buy a knife with a good edge and keep it shaving sharp with an ERU."

"For the 20 plus years as a profession and before as a Cook and outdoors man I have tried most every gadget Gizmo with carbide inserts and they are all mediocre at best and usually very damaging as other have stated. Then I used Fred's ERU..."

"I sharpened knives of my own and production blades of CM154, 440C, CPM-S30V CPM-S35VN, 1095, O1, VG-10, VG-5, VG-1 and David Boye's Detentric 440C that has huge carbides in it plus many mystery steels. This unit can be used on ALL steels! For the field it is the best sharpener of its size and configuration I have ever used."

"I have been testing Fred's lapped ERU units daily for two weeks and have nothing but great things to say so far about the construction and design of them, they do one fine job of restoring & refinishing edges on fillet to cleaver sized knives."

"For the field, they are the best thing I have seen ever, due to their compact design & ease of function. All I suggest any hunter, camper or hiker add is a black marker to help you tune in the exact edge you are after."
