I have a similar type that I made. Even soaked in used engine oil (thats what happens when you let you kids use your tools) it still grips a filter fine.I made an oil filter strap wrench once with a piece of 3/4" square tubing and some seat belt webbing. Just slotted one end through one wall long enough to hold the seat belt. Once it wraps up tight, it won't slip, and you can use an adjustable open end wrench on it.
